Body Work & Service Work

Went to this place to have some body work done on my bumper. While it was there I also got an oil change. So I was dealing with the service and body shops. When I picked up my Jeep I noticed that the airbag light was on and the horn wasn't honking like it should. These were not things that were problems when I dropped it off. They also never mentioned these issues until after I brought it to their attention upon picking up my Jeep. They they said they had noticed but ignored the airbag light and didn't know about the horn. Instead of fixing what they broke though they told me that the sensors for each item had gone out and it wasn't their fault and it would be $150 to replace! So I am supposed to believe that within the week that my Jeep was with them that 2 random sensors went out --completely independent of all the work they had done-- AND give them more money to fix the new problems!! This is completely unacceptable. I wish I had never gone to them, they are liars and now I have more problems than before I put my Jeep in their (incapable) hands.
