This credit card account exists ONLY for obtaining 0 % balance transfer/convenience checks. I am aware I pay a fee, but I do NOT make purchases on this card. The intent is to pay the entire balance off within the time frame. As of XX/XX/XXXX statement, I carried 3 balances on the card ( per page 2 of statement ). ( Total account due= {$6400.00} ) 1 ) XXXX, expiring XX/XX/XXXX 2 ) XXXX, expiring XX/XX/XXXX 3 ) XXXX, expiring XX/XX/XXXX On XX/XX/XXXX, I used a convenience check for XXXX, and was charged {$60.00}. On the XX/XX/XXXX statement, I carried 4 balances on the card ( Total account due=XXXX ) 1 ) XXXX expiring XX/XX/XXXX 2 ) XXXX expiring XX/XX/XXXX 3 ) XXXX expiring XX/XX/XXXX 4 ) XXXX expiring XX/XX/XXXX ( not sure where this came from, would think it would be XXXX ) On XX/XX/XXXX, I made a LATE payment ( due to the holidays ) of XXXX, which was to cover the XXXX. I expect I would have to pay a penalty APR for the 3 days I did not pay off that balance. However, the payment was misapplied entirely. On XX/XX/XXXX, I made another payment of XXXX On XX/XX/XXXX, I made a payment of XXXX On my XX/XX/XXXX statement, I was charged XXXX of interest, AND, my payment was not applied correctly because I still had a balance, and was now accruing interest on it. ( Total outstanding balance=XXXX ) 1 ) XXXX ( already expired, accruing at 13.74 % v, {$11.00} interest ) 2 ) XXXX expiring XX/XX/XXXX 3 ) XXXX expiring XX/XX/XXXX 4 ) XXXX expiring XX/XX/XXXX On XX/XX/XXXX @ XXXX, I called CHASE and spoke to XXXX, who transferred me to XXXX from the payment team. Although it took much explaining, they finally understood and stated they would need to send the info to the correspondence team, who would make adjustments to the fees and interest, and it would take up to 30 days for it to be resolved. On XX/XX/XXXX, I made a payment of XXXX On my XX/XX/XXXX statement, I was charged {$11.00} in ADDITIONAL interest, even though by now, the entire promotional balance expiring XX/XX/XXXX should have been paid off. The statement showed the following : ( NOTE : CHASE had not done anything at this point ) ( Total outstanding balance=XXXX ). 1 ) XXXX, ( already expired, accruing at 13.74 % v, {$11.00} in interest ) 2 ) XXXX expires XX/XX/XXXX 3 ) XXXX expires XX/XX/XXXX 4 ) XXXX expires XX/XX/XXXX On XX/XX/XXXX, I called CHASE again, and spoke to XXXX in customer service. She stated she read the notes and would transfer me to XXXX, and account supervisor and payment team specialist. Again, after explaining, she agreed that the payment back in XX/XX/XXXX should have been applied to the entire XXXX but was not, and it needed to be changed. She stated a case would be assigned to one person, who would follow up with me within 3-7 business days, but to wait 10 business days, and call the number on the back of my card with questions, or check online to see if any changes were made. On XX/XX/XXXX, I made a payment of XXXX On my XX/XX/XXXX statement, I was AGAIN charged {$7.00} of ADDITIONAL interest. However, CHASE had credited me the following interest charges : {$0.00} {$11.00} {$0.00} {$11.00} ( ( Total outstanding balance=XXXX ) My balances were as follows : 1 ) XXXX ( already expired, accruing at XXXX ( v ) ( d ), {$7.00} in interest ) 2 ) XXXX expires XX/XX/XXXX 3 ) XXXX expires XX/XX/XXXX 4 ) XXXX expires XX/XX/XXXX On XX/XX/XXXX @ XXXX, I called CHASE again, and spoke to XXXX. Again, I had to explain my problem over again, and 19 minutes later, she transferred me to XXXX, who was a manager in the payment team. I explained to XXXX, and she again agreed that I should no longer be paying interest, that it should be reversed, and I told her that all subsequent payments were also applied incorrectly. On XX/XX/XXXX, I made a payment of XXXX On my XX/XX/XXXX statement, I again paid interest {$5.00}. The total outstanding balance was XXXX. Breakdown was as follows : 1 ) XXXX ( already expired. accruing at XXXX ( v ) ( d ), {$5.00} of interest ) 2 ) XXXX expires XX/XX/XXXX 3 ) XXXX expires XX/XX/XXXX 4 ) XXXX expires XX/XX/XXXX Again, the payments, in excess of the minimum payment were never applied correctly, even after the interest was credited back. Today I will pay whatever is outstanding and expiring by XX/XX/XXXX, only so this problem is not once again compounded. I have been more than patient with CHASE, and need help in resolving this issue by an outside agency. Thank you.
