I had the windshield replaced in my SUV and in the process the shop damaged several parts of the body (chipped paint, dents, etc.) A dealer estimated the repair costs at $1400 and the shop admitted to the damage. However they do not want to pay that much for repairs so they have sent it to a 'guy' they work with who botched the job even worse. They won't even give me the guys full name or address. I want it fixed by a proper body shop but they say they have the right to use whoever they want. What's my possible courses of action?
