Ah, but they did. They installed a customer supplied clutch and flywheel. Right or Wrong the work was still performed. If you go into the mall and steal a shirt from gap that has a stain on it.... doesn't matter that the shirt wasn't correct, you still stole it. I'm More playing devils Advocate here as he did the only option left to him because this shop didn't play ball in any way shape or form. With them not agreeing to look further into the problem, then letting the car go without looking further into the issue then after finding they were in the wrong refusing to refund or partial refund. This shop clearly has a management issue and is in the wrong. Lets see how good they are at disputing credit card back charges. Hopefully for the customers sake, not very good at it.
