Minor bumper replant

Do not go to this shop. They repainted my corner bumper and had caused my doors to have weird water marks that they refuse to fix. I have a brand new BMW X 5 and my front corner bumper was scratched parked on the street one day. So I decided to have them fixed it and it was minor enough. When I pick up my car there was strange/weird water marks all over my driver side car door. They said they will fixed it. After I pick up my car second time, they did nothing about but just polished over it, and they refuse to fix it again. The bumper fix was around 260, but now to fix my doors probably over 1K.
