Body repair and paint

I went in for a body repair and paint. When I picked up my car the paint was expanding and looked like someone took a steel brush and scratched back-and-forth on my entire bumper. He tell me oh, don’t worry take it home come back in a month and he would buffet out. I came back again and it came out worse than the first time.. he told me what do you expect you want a cheap job you get a cheap job they cost me $1800.
