Bank of America Credit Card Complaint

Bank of America Credit card department,

Other fee Massachusetts

During my - billoing cycle, BofA charged me $30.00 in interest, even though I paid the previous month 's balance in full, as shown on the - billing statement ( attachment ). This is my first inquiry. Also during my - billing cycle, Bank of America issued me a credit of $10.00 for a fee they waived from my account. Therefore, at the end of the billing cycle in -, I paid my full balance minus $10.00, assuming that the $10.00 refund would apply towards my account balance. However, in the - statement, I was assessed an interest charge of $31.00. When I called Bank of America to ask why, they said that I had underpaid by $10.00 because the $10.00 refund of the fee did not apply until the next billing cycle -. My second inquiry is


I then asked how a $10.00 underpayment could lead to $31.00 in interest. They told me that underpayment on the account causes any purchases after the underpayment to be considered part of the average daily balance, even if they are part of the current billing cycle which is normally subject to the usual grace period for payment. This is the third inquiry. This explanation does not make sense to me, nor can I find it documented in the Terms and Conditions of the card. Extended questioning of over - minutes with the customer service representative also did not yield any clear answers - they just kept referring me back to the Terms and Conditions.
