GreenVille Auto Sales Inc

Alright so I go in for a big repair. Spend a good deal of money ($3k). This shop does mediocre work as best. I was given what I thought was a great warranty, but once the work was done the warranty does not cover overheating and oil leaking (something that was not told to me before going into this fix). I get my car back, car leaks oil really bad, and he says I have to come in and spend more money. The guy didn't hook up the climate control system either. So I take it in, he fixes it free of charge, and it takes him 3 days to hook up my AC again. And now that its cold out, I tried the heat and it doesn't work. Who repairs cars with out making sure everything works the way it did before completing the transaction? I am not going to take it back to then be stranded with out a car again for 3 days for a simple issue that was his fault. Prices seem fair, but work done does not match.
