I was called from XXXX on XXXX/XXXX/2015 at XXXX reguarding a debt with XXXX XXXX XXXX. The person who called me did not identify the name of the company and simply asked for me by my first and last name. When I said yes XXXX said that she was calling for a account with XXXX XXXX XXXX and I owed {$1000.00} something then went into settlement and payment options so much as offering me a settlement at 50 %. There was no mini Miranda given at any point and I was not notified the calls could be recorded and did not verify who I was by using verification methods such as last XXXX of the social security number or mailing address. I told her I would call back. I recieved a call at XXXX XXXX XXXX/XXXX/2015 and the same person left a voicemail stating I did not call her back. I called back their number XXXX ext XXXX. She again did not identify the company name. I gave her my phone number and she looked up the account and again simply asked for me by first and last name. I asked how much is owed and she went right into the account. I asked her if she was a debt collector and she said yes so I asked why she would give out personal information without verifying who i was. She stated that she asked for me by using my full name middle name and suffix included which she did not. I told her that she did not disclose a mini Miranda as well nor state the calls may be recorded. She said she didnt have to give me a mini Miranda and I asked to speak to a supervisor. She said she would transfer me and she then hung up. I called back and she said she did not mean to hang up with sarcasm in her voice and transfered me to a supervisors voicemail. I left a message stating that this is the XXXX time in less than XXXX hours that information has been given out without proper verification and have not received a call back. It took me looking up the phone number on XXXX to figure out the name of the company is National Credit Adjusters and this is not the XXXX time they have done this. I could have easily given the phone to someone next to me and they would have given any information that the person asked for.
