Clutch replacement

The clutch went out in my daughter's meticulously maintained 1990 Corvette. I called around for the best price. Cliff here at Ellis road automotive. Gave me the best price and said he was capable of doing the job. I picked up the car and it had a extremely loud rattle. He said it would go away don't worry about it. It got louder. I took it back and he yelled at me and said there's nothing wrong with it and if he takes it apart I have to pay him for his time. He took it apart told me I had to come look at it. I told him if I knew what I was looking at I wouldn't have called him in the first place. I looked at it with him. We both noticed that he installed the throwout bearing incorrectly and it was crooked and off center. He said he would fix it. He called me and said he put it back together but it's still making the noise. He damaged the transmission in my daughter's Corvette and admitted to it. I asked him how we were going to resolve this? His reply was: "try and sue me I'm going to retire soon and I don't care"! On top of that, he threw the car keys at me and told me to get out. How's that for good service? I paid $1,000 for him to $5,000 worth of damage.
