After many years of being a BOA customer, and paying outrageous interest each month, I found out that they charge interest on your revolving balance and every month the revolving balance is higher than my statement balance. I called to have someone explain it but it's a maze to get a straight answer. I only looked into this over the last couple of months, but January, February and March, the interest was charged on approximately, a $200.00 higher balance than my statement balance. Their calculations are charging interest, putting on the balance and then charging interest on the higher amount, as in, on top of interest that was already charged. I HATE BOA. I am writing to whoever I can to see if this is legal. I need a forensic accountant!
