USAA Auto Loans IS A JOKE

I traded in a vehicle on April *, and purchased another vehicle. USAA rolled my negative equity from original loan (which was financed through USAA) into a new loan which included the new vehicle. Original loan is still open, and I am in collections now due to unpaid original loan (again, which was rolled into new current loan which I am paying). USAA and dealership keep mailing checks back and forth to pay off loan - wrong amounts, wrong loan *'s--it's ABSURD.*Been a member over ** yrs, I have IRA's, Savings acct's, Credit Card (which has now been suspended due to nonpayment on old auto loan), Insurance, and auto loans with USAA. I have called USAA no less than ** times about this, the dealership, and have gotten no one to understand I AM NOT THE ONE who has the money USAA wants...it's the dealership. How am I legally responsible for the old laon once I signed the new loan???? If this hits my credit, I will pull every account I have with USAA*Mike

***yrs, IRA, Credit Card, Savings Account, Auto Loan, Auto Insurance

I have called USAA no less than **x...almost daily.*Spoken to "Executive Team Members" who are completely useless
