There is a legally binding document showing the date the receiving dealer accepted the trade in vehicle.
It is called a Bill of Sale.
Account shows paid in full and I was even sent a refund check from the lender for overpayment.
Anyway I have disputed it and provided documentation to the Credit Bureau showing that payment was current at trade in and a copy of the Bill of Sale showing trade in date.
The real bitch is the loan on the new vehicle is carried by the same lender with a date of effect of 8-24-18, the new loan was already approved and in place when the old vehicle was physically traded in.
Dealer playing fuck-fuck games, they likely didn't pay it off until they sold it.
That's not my problem.
