Barclays Credit Card Complaint

Barclays Credit card department,

Virginia

The credit card company pricelinereward visa card issued a check in error on - -, - for $4800.00, despite the account was closed on - -, -. I called the company regarding the check and I was told this was a reward check and that I can deposit in into my account. They did n't give any other explanation of why I was receiving the check besides that it was my money so I deposited the check. On - - -, I recieved a letter stating that the check was issued in error to my account and that I owe them $4900.00 including interest of $140.00. So they are asking me to pay $140.00 in interest. They waited 8 months from - -, -, when they posted the check in my account, to inform me that they credited my account in error. I have already paid their $4800.00 back and they insist that I still owe them $140.00 for interest. To me this seems fradulent since they said it was my money and that I could deposit the check and they also waited 8 months to send me a letter stating it was an error on their part. I never recieved any statements prior to the one I recieved in - - stating that there was an outstanding balance in my closed account. Now they are insisting I pay interest on a $4800.00 check and I refuse to pay the interest. Please help resolve this issue. Thank you.
