The payoff process used by USAA breaks the XXXX XXXX credit card XX/XX/XXXX. I made payments to the credit card for XXXX from XXXX time frame and all payments were applied to a balance transfer rate of 1.9 % instead of the 18.15 % interest rate. Anything over the minimum payment is to be applied to the highest interest rate on the account. Furthermore, I went back to previous statements dating back years and discovered USAA charged full monthly interest on purchases even if the purchase balance existed for a 5 days ( for example ). Over a period of years, both of these equate to large quantities of interest being wrongfully charged to my account.
