Finishing Touch Auto Detailing

I went to get my headlights tinted and they didn't mask around the headlights completely so when they sprayed the tint on, overspray got all over my cars finish. It looked terrible because the overspray was a white ish color and my car is black. When I went back and asked them what they could do about it, they insisted it was not their fault and said there was nothing they can do. He said " it will wear off eventually" there seemed to be no sense of professionalism. At least they could have admitted to not masking around the headlights correctly. Instead they said "that's how it is" and sent me on my way . Very rude. Terrible service
