I purchased an automobile in or around XXXX 2015 from a dealership. The vehicle had experienced mechanical problems, and so I returned the vehicle and the dealership accepted the return minus their restocking fee. Well, I had told the USAA customer service department about the vehicle being returned. I have also been XXXX and told them that as well. Please assist me in dealing with this matter. On XXXX XXXX, 2015, USAA debited a car payment from a joint account without my authorization.
