Product: Credit card or prepaid card

Good afternoon, My name is XXXX XXXX and my account number is XXXX XXXX XXXX XXXX with Comenity- XXXX XXXX XXXXl. I am writing to DISPUTE the finance charges that were added to my account on XX/XX/XXXX, in the amount of {$1000.00}. I have maintained a compliant account with you all since opening my credit account and consistently paying {$130.00}, monthly. In XX/XX/XXXX, I purchased a new home and the balance of this account was included in my loan. My banking institution contacted you all and was advised my balance was {$1600.00}, as XX/XX/XXXX. Per my account, that payment of {$1600.00}, posted to my account on XX/XX/XXXX. I was under the impression my account was satisfied. On XX/XX/XXXX, a late fee of {$28.00}, was posted to my account. As I stated earlier, I purchased a new home and my address was not updated. When I received mail from my previous residence in XX/XX/XXXX, I contacted you all advised of the situation and that I was not aware of the {$28.00}, late fee added to my account. A member of your management team advised the {$28.00}, late fee would be waived and this would bring my account current and I would not owe anything. This discussion happened prior to the expiration of my promotional balance date of XX/XX/XXXX. The fee of {$28.00}, was not waived prior to the expiration of my promotional balance and the promotional finance charges in the amount of {$1000.00}, was added to my account on XX/XX/XXXX. The credit of {$28.00}, was not added to my account until XX/XX/XXXX. Another fee of {$28.00}, noted as promotional to revolving, was added to my account on XX/XX/XXXX. The bill that I received on XX/XX/XXXX, for XX/XX/XXXX, with a past due date of XX/XX/XXXX, as you still didnt have my current address, displays a balance of {$56.00}. I did not learn the interest was added to my account until XX/XX/XXXX, when I contacted you all again to resolve this issue. 
In summary, I have been XXXX finance charges due to the expiration of the promotion I was under in error and Im DISPUTING, those charges. I paid the balance of {$1600.00}, and was not aware of the {$28.00}, late fee attached to my account. Once I became aware of the {$28.00}, late fee, I contacted you all and advised by your management team that the late fee would be waived, and I didnt have a balance prior to the expiration of my promotion. The fee was eventually waived but it was after the interest charges were added to my account. If you would correct this error and remove those charges from account. 
Lastly, after speaking with several Senior Managers with your organization, I was instructed to write and DISPUTE the finance charges added to my account. I had to pay {$41.00}, on XX/XX/XXXX, to prevent reporting of delinquent payment to the credit bureau. This whole situation has been overwhelming and frustrating at the same time. I have always been responsible when it comes to my credit and this does not show me being financially responsible. Your company states, Were committed to making each experience with us exceptional and you have award winning customer care. If would you resolve this situation and removed finance charges added in error and provide the customer satisfaction needed for this situation. 
Respectfully submitted, XXXX XXXX Account # XXXX XXXX XXXX XXXX
