payoff issue big problem

[sean7799]

I purchased the truck new for 23000 with tax ,title and tag included for company A (first loan was provided by a credit union to company A). I traded in the truck 5 months later for a new toyo camry for 18000 with company B. on the paper work company B offered me 19000 for the truck and their was a little negative equity rolled over on to the car. Company B received the check from wells fargo for 23380 for the negative(5000) roll over and the 18000 for the camry = 5000 + 18000 +fees= 23380 . (wells fargo provided the second loan for the trade in.) Company b was given the check on 11-21-2007 and has not made the payoff to the first lien holder of the truck which is the credit union. It's been 45 days since the transaction. They told me they were not able to get the 19000 they promise for the trade in on the truck. They were only able to get 15000 and were waiting for people to by more cars to make up the difference. How can i fix this
