Went to dealership in march to trade in an suv for a different kind of suv, drove off car lot with new vehicle. Credit score was 627. Two weeks later received phone call from previous lender b/c trade wasn't paid off. Contacted current dealer, stated they would pay off trade asap. They waited and paid off trade 2 months later. In the meanwhile, several denial letters were sent from a number of banks. Didn't here from dealership, and they never returned my calls. I went there to find out why haven't i received finacing yet. I was told because finance manager dropped the ball, and credit score went down to a 427 because of trade not being paid off, and no one told me to continue to pay company. I was ignored instead. I am not satisfied with company and don't want to give them my business. General manager sent letters to credit 3 companies trying to increase score. As of today no one called, car is not financed.
I signed three buyers orders with different rates and paymt amounts.

Which contract apply?
I there a certain time that dealer has to find financing if so what is it?   
After 30 days is credit app. still vaild? Because I only sign one (in March)
Can I take the new SUV back because they can't get it financed even though they paid off the trade?
Can I ask for my old SUV back or the value of it?
Since my score is very low because of this can I receive compensation for my damages?
I can't refi my home or finance anything for a while?
What are my options?
How do I get out of the contract?
Was there a breach on the dealers end?
