I made a payment of {$950.00} in XXXX XXXX and realized that I did not have funds in my bank account. I called Bank of America to cancel the payment where I was informed they would give me a refund of {$950.00} on XXXX XXXX, XXXX. Bank of America incorrectly categorized this refund as a purchase made on the card and subsequently charged me interest for the next consecutive 3-4 months because of the way payments are applied. Spoke with three different managers and three different representatives each month and they all made notes in my account detailing that I should not be charged interest because it was a bank error. The last manager noted that the {$950.00} was going to be lumped into the balance transfer promotion and this problem would go away. After 3 months, the problem remains and I keep getting charged interest. I paid the promotional balance in full that ended on XXXX XXXX, XXXX.
