Bank of America Credit Card Complaint

Bank of America Credit card department,

APR or interest rate New York

I received a bill from my credit card company in -. I paid the statement balance in full before the - payment due date. On my next statement that I have received, with a payment date of -/-/2016, I am being charged interest on the paid off balance from -. They are telling me that interest was still acrueing (? ) from the - statement closing date until the day I paid it in - - " Residual interest ''. I have other credit cards, and they do n't do that when I pay off the balance. I used a HELOC earlier in the summer to pay off credit card debt, and none of the cards tried to get extra interest money when I paid off the balances. Not sure what has changed in the banking industry that they think they can get away with this.
