JPMorgan Chase Credit Card Complaint

JPMorgan Chase Credit card department,

Delinquent account Virginia

In - a holiday purchase while travelling in - was made in the amount of $420.00 using - Chase VISA. The amount plus applicable interest charges were paid in full via a telephone transaction handled by a Chase Specialist. The next billing cycle, I was charged additional interest & late fees. I called to complain since the payment was paid in full. According to the Chase Specialist, the additional interest would be waived & late fees reversed. The next billing cycle, the late fee reversal posted but the additional interest in the amount of $6.00 was not waived. In fact, it showed as past due and additional interest in the amount of $.00 accrued. Once again, I called to complain. This time the Chase Specialist was apologetic and advised that the Agent who processed my payment in full erred. She should have told me that she was unable to provide a Pay in Full Amount since interest is calculated the following day automatically by a computer system. I had enough. I asked whether this fiasco was impacting my credit. She said not at the time but strongly advised that the now $7.00 be paid immediately. I proceeded to pay. Well, several months later, Chase reported the account - late for $7.00 to all - repositories negatively impacting my credit. My efforts to amicably resolve this issue with Chase has been to no avail. All of the Chase Specialists state that they agree with my position but do not have the authority to resolve the issue. The matter can only be handled by a Manager in a Special Collections/Credit Section. Each time, different Manager ( s ) state in a defiant tone that the matter is closed and I need to wait 7 years for it to drop off.
