Company asking for card details to refund over email
If it is a well known company that wants to give you a refund, I would not worry about giving them your credit card number.  However, I would never type my credit card number into an e-mail message. E-mail messages are very insecure, and can be read by many people along its way to the destination. They also can be archived in many places, meaning that your number will continue to be posted out there for someone to grab in the future.  If you need to give this company your credit card number, do it over the phone.  Having said that, ultimately you are not generally responsible for fraudulent charges if your card number is stolen and misused. I've had so many fraudulent charges, despite my being relatively careful with my number, that I don't really worry much anymore about losing my number. I just check my statement for false charges, and when they happen,  the bank cancels the charge and issues me a new number. It has happened to either my wife or I maybe 5 times over the last two years. I used to work for a online payment posting company. Anytime a payment is made via Credit Card to a company that does not have PCI DSS(aka the ability/certification to store credit card information) there is a MD5 checksum(of the confirmation code, not the Credit Card information) that get sent to the company from the processor(billing tree, paypal, etc). The company should be able to send this information back to the processor in order to refund the payment.  If the company isn't able to do this, to be honest they shouldn't be taking online credit card payments. And by all means do not send your credit card information in an email. As said above, call the company's customer service line and give them the info to credit your account. "Personally, I would just dispute this one with your CC.  I had a situation where a subscription I had cancelled the prior year was billed to me.  I called up to have a refund issued, they couldn't find me in their system under three phone numbers and two addresses.  The solution they proposed was ""send us your credit card statement with the charge circled,"" to which I responded ""there's no way in hell I'm sending you my CC statement.""  Then I disputed the charge with the CC bank and it was gone about two days later.  I partially expect to have the same charge appear next year when they try to renew my non-existent subscription again. Now, whether or not this is a normal practice for the company, or just a call center person making a good-faith but insecure attempt to solve your problem is irrelevant.  Fact of the matter is, you tried to resolve this with the merchant and the merchant asked for something that's likely outside the bounds of your CC Terms and Conditions; sending your entire number via email.   Dispute it and move on.  The dispute process exists for a reason." "While I agree with Ben a lot I feel like his answer is really poor here. You do not call a number to give your credit card information out for a refund.  That is ridiculous.  Just from his answer - he has had 5 cases of fraud lately - you should know that you shouldn't follow this advice. I personally don't ever give my credit card number over the phone, unless it is the very very very last resort.  It is not just about money and safety but it is about time.  Every time that you give your number out over the phone there is a chance that the employee on the other end (by either scam or legitimate business) will use or sell your info.  So you need to determine if the time saved by doing a transaction over the phone is worth hours/days of your time if your card has a fraud issue.  And note that fraud sometimes is easily negated, but if done smartly can be hard to prove via a quick call or email to card company. What should you do? Tell company that you will simply get the refund through your credit card company. And if we go back to time element...  You fill out form on card website.  Card company goes back to vendor and says - ""Why are you asking for card numbers via email?""  Card company either cancels vendor contract or more likely helps them understand the technology available so they don't have to do this.  Therefore that quick form that you filled out will now keep this company from bugging you again.  By going through their archaic ""systems"" you are enabling their behavior." "A bona-fide company never needs your credit card details, certainly not your 3-digit-on-back-of-card #, to issue a refund.  On an older charge, they might have to work with their merchant provider.  But they should be able to do it within the credit card handling system, and in fact are required to.  Asking for details via email doesn't pass the ""sniff test"" either.  To get a credit card merchant account, a company needs to go through a security assessment process called PCI-DSS. Security gets drummed into you pretty good.  Of course they could be using one of the dumbed-down services like Square, but those services make refunds ridiculously easy.   How did you come to be corresponding on this email address?  Did they initially contact you?  Did you find it on a third party website?  Some of those are fraudulent and many others, like Yelp, it's very easy to insert false contact information for a business. Consumer forums, even moreso.  You might take another swing at finding a proper contact for the company.  Stop asking for a cheque.  That also circumvents the credit card system.  And obviously a scammer won't send a check... at least not one you'd want!  If all else fails: call your bank and tell them you want to do a chargeback on that transaction.  This is where the bank intervenes to reverse the charge.  It's rather straightforward (especially if the merchant has agreed in principle to a refund) but requires some paperwork or e-paperwork.   Don't chargeback lightly.  Don't use it casually or out of laziness or unwillingness to speak with the merchant, e.g. to cancel an order.  The bank charges the merchant a $20 or larger investigation fee, separate from the refund.  Each chargeback is also a ""strike""; too many ""strikes"" and the merchant is barred from taking credit cards. It's serious business.   As a merchant, I would never send a cheque to an angry customer.  Because if I did, they'd cash the cheque and still do a chargeback, so then I'd be out the money twice, plus the investigation fee to boot." Definitely push for a check, they may not do anything nefarious with your credit card number however someone else may be able to read the email before it gets to its final destination. It's never safe to give out credit card number in a less than secure interface. Also, if this is a well known company, then the person interacting with you should know better than to ask for your information through email.
In the UK there is a significant difference between taking money out of a bank account and out of a credit card account. Banks typically require explicit authorisation before they will transfer money out of a bank account - for example a direct debit agreement. (North American banks are much less strict, and will transfer your money to any reasonably reputable financial organization who asks for it - don't get me started!). However credit cards run very differently. Essentially the onus is on the vendor to get the authorization, which is why you can sign a credit card slip at the corner store, or give your credit card details over the phone, or fill in an online form, and have your credit card account charged. When you signed the credit card agreement you agreed to let people do this. It's also why the credit card company will reverse a transaction if you claim it was unauthorized. So essentially PayPal is like the specialty store you phone up to order something and give your credit card details to - they have just as much authorization to charge your account. Your only protection is that the credit card company will investigate any transactions you claim are fraudulent, and will reimburse you if it is- even if they can't recover the money themselves. The simple answer is that you have to read the terms and conditions when you sign up for a checking account at the bank. The process of fraud investigation varies from bank to bank.  Ultimately most banks will refund the money if you are not deemed negligent. Some banks offer quick reimbursement during fraud claims, but many will not refund the money until the investigation is complete (which can take several weeks). Checking accounts are terrible security problems. If you're looking for ways to avoid a hassle, stop writing checks and using ATM/Debit cards. If you must send checks to pay bills, use the bill-pay system that is now common with most banks (they use a service to send checks on your behalf and don't even charge you for postage unless you ask for expedited processing). "There may be a confusion here: I don't think you can get cash back at a register with a credit card. See http://www.cardratings.com/can-i-get-cash-back-when-i-buy-something-with-a-credit-card.html Cash back is only available with a debit card. With a debit card, the money comes directly out of your account at the moment of the transaction. With a credit card, the CC company loans the money to you and you get a monthly bill. You can get cash advances at ATM machines, but  typically comes with hefty fees and exorbitant interest rates, so I strongly advice against this.  There are ""Cash  Back"" credit cards, but that means that you get a percentage of your purchases refunded as cash (or points)." "Here we go again! Why, oh why, would someone just open a bank account in your name with that much money for no good reason?  Unless there's a very rich relative in your family tree, this can not come to a good ending.  Besides, if this was money being left to you by someone as part of an inheritance, you'd hear from attorneys from the estate. Notwithstanding everything @NickR posted about the details of what makes it suspicious, ask yourself why a banker would contact you by email about an account with this much money in it.  The bank would, at the very least, send you a registered/certified letter on official stationery.   So what happens here is when you give them your banking information, whoever it is that's doing this will clean out your account, and that's for starters.   They will ask for enough information to steal your identity too, and if you have good credit, that'll be gone in a heartbeat. The best scams (meaning the most successful ones) always appeal to peoples' greed, using large amounts of money that just miraculously belong to the victim, if only they'd give a little information to ""transfer"" the money.   Worse yet, most of these scams will come up with some kind of ""fee"", ""tax"" or other expense that you have to pre-pay in order to make the transfer happen, so this just adds insult to injury when you find out (the hard way!) you've been scammed. DO NOT reply to the email you received or, if you already have, don't send any more responses.  If they think they may have you on the hook then they won't stop trying, and it will become very messy very quickly. THIS IS NOT REAL MONEY!  It isn't yours, it doesn't really exist, and all it will do is come to no good end if you go any further with it. Stay safe, my friend." I cannot speak specifically to the Netherlands or the UK specifically, but my prejudice has me believing that there would be more consumer protection in those two countries than that we have here in the the US, certainly not less. Debt collectors mostly do their job by bullying.  Here in the US they are mostly toothless and typically obtain payments when they invoke an emotional reaction.  In your case they are attempting to invoke fear.  Legal action over €400?  Get real.  It will cost them 20 times that to bring action, and they are equally likely to get a sympathetic judge to toss out the case. Now you very well know you should have returned the box, please don't be coy.  If you still have it, you should attempt to return it.  If not you should attempt to settle.  Offer them €80, going no higher than €160.  Get it in writing, that this satisfies the debt and use either a one time use credit card or a bank check/money order. It's a pretty good tip. People are often telling you the answer but not explicitly. Example:  You call about bad service and demand a refund. The employee tells you:  I'm sorry, sir, I can't give you back your money.  But maybe he actually said:  I'm sorry, sir, *I* can't give you back your money. Maybe someone else can?  I'm sorry, sir, I can't *give* you back your money. So not give but trade?  I'm sorry, sir, I can't give you back your *money*. So what can you give? I would go speak to the bank manager. With Wells, you have to make sure it is the bank manager and not a service manager or something you are talking to (I learned that a few months ago).  Tell her/him exactly what happened in detail and that you want the credit card closed and the credit inquiry removed from your credit report. Further, say that once all of that is done, you will decide whether to continue banking with them and whether any legal action is appropriate.  If they give you any kind of push back, I'd get advice from a lawyer. The truth is they did open an account against your expressed wishes and it required them to check your credit so it does constitute fraud unless they can produce a signed document saying you agreed to the card.  Edit: I just saw that this happened about a year ago. It may have been easier if you had done something at the time and may be more difficult if you've used the card in the meantime. "I think your confusion comes from the negative impact when a creditor writes off your bad credit and ceases attempting to collect it. ""Chargebacks"" as you call them are an attempt to undo fraudulent charges on your card, whether from stolen credit card info or from a merchant who is using shady business practices. For what it's worth, if you joined on December 20, January 20 seems like a reasonable date for the next billing cycle, with the December 31 date reflecting the fact that their system couldn't automatically bill you the day you joined. I also think it's reasonable for you to ask them to refund the bill for the second month if you do not plan to use their gym further. So the dispute seems like a reasonable one on both sides. Good luck."
