Barclays Credit Card Complaint

Barclays Credit card department,

Payoff process Georgia

I have a UPromise MasterCard. On - -, 2015, I made a payment over the phone from my bank account to pay off my entire current balance on my UPromise care, a little over $9000.00. By their records, the payment was processed the next business day - -. However, even though they have processed the payment, they will not clear my account and are continuing to charge me interest until - - at -! The UPromise agent I spoke with over the phone was unable to explain to me the rationale behind this. This seems like an immoral if not illegal practice to take payment, hold both my money from the bank and to charge me interest for a week. That dollar amount is too small to financially be worth my time in small claims court, but if UPromise is doing this to other credit card holders, they stand to make a pretty large sum of money.
