Collision repair

This body shop is absolutely terrible.I had to make about five trips so far and i still have problems with my repair. My delivery date was pushed back week after week and when I finally got my car back they had missed many problems and had not fully assembled many of the parts they had taken out. For example they unplugged an audio amp I had in my car which they shouldn't have even touched and when they returned the car to me the ground and LIVE power cable were just sitting next to each other just ready to burn my car down. When I brought that up to them the two kids that were working on my car starting laughing and saying to each other, "I told you not to touch his s***, man." Very unprofessional all around. When I arrived at my home my car was in a full smoke because they had not put coolant in the car.... They completely missed the damage underneath the vehicle so I had to go back and point it out myself and be without my vehicle once more. I am now going to get rid of the car at a huge loss anyone can see that this "repair" is awful.
