Some years ago My wife bought a car, she worked for a bank and had the bank finance already approved.
As I was a mechanic I took it for a test drive, salesman rode in the back, I found a bad power steering leak and told them we'd buy it IF THAT WAS FIXED.
They fixed it and we took it home a day later.
A week later the dealer called and told me "The financing didn't go through, and I'd have to bring it back and pay more money". (Remember it was financed BEFORE it was bought)
I laughed at the telephoner and called him an ignorant ass*ole, and hung up, Mind you, the dealership had been told it was financed when we got it.
They called back threatening and I laughed at them, louder with each call, Finally I got a call from some City Cop, they Told him I'd stolen the car, and I told him what had happened, he didn't like it, and was upset that they had tried to use the Police in their Scam, months later I finally got a written apology from the dealership and they said that somebody gotten fired.
I didn't give a shit, we never went back, I later heard they went out of business. GOOD RIDDANCE.
After reading the report, I strongly suggest you call the Attorney General's Office (County, or State if there's no County AG)
