Auto Show Sales & Service

I bought a car from Auto Show Sales & Service a month ago and traded in my old car. They couldn't get me approved for anything else, so I settled for a car I didn't really want. The car had bald tires, worn brakes, and noticeable damage that I couldn't see because it was too dark. Two days later, the alternator died. I asked to cancel the sale and get my old car back, but they said they couldn't because they had already sold it wholesale. They did replace the alternator, but I had to pay for all the other repairs myself. When I went to get my transfer plates, they made me pay a title fee even though I had the title with me. They later asked for the title and gave me a check for the fee, but the check bounced. They lied about selling my old car wholesale because they didn't have the title. It seems like they broke some laws.
