USAA Savings Debt collection department,

Credit card Cont'd attempts collect debt not owed Debt was paid Alaska

I had Auto Ins with USAA. I had my monthly payments charged to my USAA credit card, I paid my credit card each month. Last - 2015 I had a double billing. Instead of approximately $62.00 ( a normal single month ) it was for $120.00. I was told they had changed the way their billing was done and the double payment was for the months of - and - 2015. It was a one time double billing. I also have it in writing from - of their Customer Servicer Reps. I paid this double billing on - -, 2015. I sold my car at the end of - 2015 and notified USAA right away and cancelled my insurance. Thus ending any further payments. They continue to bill me for that last " - '' month period. Claiming I never paid it. I have offered to send them the cancelled check, I have asked and told them to STOP calling me, they continue to call. No matter what I say to them, so matter how I explain it to them they just do n't get it. I paid them! I told them flat out I do not owe them anything and I will not pay them and to stop calling me. They continue to call me. I want this to stop, please! Enough is enough ... ..
