Your car was worked on by idiots. I'd have a hard time bringing it back there too, but you need to give the shop a chance to make it right before doing anything else. Let the insurance company know you are not happy. If the shop can't resolve it, you will need to become a thorn in the side for the insurance company until they do something.

I can sort of understand the paint problem though. When I got an estimate to get some body work done, the guy was very up front about the finish. They use the original color code, but the existing paint on the car has 20+ years of fade, so it tough to match it exactly.
