Bank of America Credit Card Complaint

Bank of America Credit card department,

Transaction issue Florida

I have been a Bank of America customer since - and never had an outstanding balance in my - credit card. On - -, - I took advantage of a promotion of a 0 % cash advance. I paid $600.00 fee for a $15000.00 cash advance payable in - - at 0 % interest. In my following statement on - -, - I was charged $44.00 for interest, even though I had paid in full for my purchases. When I called the bank, I was told that my payment was applied to the cash advance balance and not my purchases, thus the interest on my purchases .... This to me is clearly a scam or misleading promotion since I am being charged twice the interest. Bank was unwilling to solve my problem and suggested to stop making purchases with my credit card to avoid future interest charges.
