Product: Credit card

I purchased an automobile audio system from Best Buy on XX/XX/XXXX. I charged the {$430.00} purchase to a Best Buy credit card provided by CITI Bank. XXXX  account is a XXXX XXXX, which allowed me XXXX  months to pay the total balance without incurring any interest as long as I paid a minimum amount each month. I made all of the payments in a timely manner, and of an amount more than the minimum required. I made the first payment of {$25.00} on XX/XX/XXXX. Another payment on XXXX, XXXX, XXXX of {$50.00}. A payment on XX/XX/XXXX of {$40.00}, then the XXXX payment on XX/XX/XXXX od {$40.00}. The XXXX payment was not due until XX/XX/XXXX so, the bank refused to credit the account for the XXXX payment, and treated it as an extra XXXX payment. I filed a dispute with the bank for not properly crediting my XXXX payment. I made the XXXX payment of {$30.00} on XX/XX/XXXX. A LATE FEE of {$29.00} was reversed.
