I mailed a check for {$300.00} to XXXX XXXX Bank on XXXX/XXXX/2015. I forgot to sign thecheck. I never got a call from them. On XXXX XXXX after 3 weeks on vacation I find the check in my mailbox.The correspondence has no explanation just the check. I call XXXX and I am told everything is fine so I make a payment of {$350.00}. They credit me back late fees so I am thinking everything is fine. I check my credit report and find the account is delinquent late 107 days. No phone call or email. I am glad they are using technology. They charge me ridiculous interest and pocket the money and provide zero service. Its a {$900.00} credit card. Are they kidding me? How about a XXXX time exception and remove the deliquency and late fee from my credit report? They tell me they are obligated to report it to the credit agencys. Yes, this is my fault I did not sign the check and should have called them. I was out of the country and off the grid. This is the result. Now my credit is ruined my score is under XXXX. Is there anything you can do to help me? This is on all XXXX credit bureau reports .... EquifaxXXXX
