I have a cash advance balance on my credit card with an extremely high interest rate. I pay more then the minimum every month and per my statement anything over the minimum is to be applied to the highest APR. Last month I paid the minimum and then made a lump sum payment equal to the amount of the cash advance to get rid of it. Bank of America applied only {$500.00} to the cash advance and the remainder to the lowest APR balance. I went back over the last years statements and they have done this every single month causing my cash advance balance to skyrocket with interest while never allocating any of my payments to that higher APR.
