Volvo Cars Orange County

I brought my 2005 Volvo s60 in to get a headlight replaced because I was having problems replacing it myself. I asked if I could watch the repair man install it to see if he had any tips on how to install without hurting my hand. They were courteous to allow me to watch, but I swathe repair,an "rip" the air intake out of my car, he replaced the light and tested the light to find there was an "electrical" problem. I then left and "trusted" the repair man, believing that since I was at a "Volvo" dealership they new my s60. 2 hours later I went back to ask what is the problem and the repair man insisted that the problem was a "computer" problem and it would be $800 to fix. I then asked "did you check the fuse" and he then responded with telling me that there was no fuse and showed me the electrical diagram. As I looked at it, with my background in electrical engineering, I responded with there is a fuse. I said no more repair to be done and still had to wait 45 min to get my car back. As soon as I got the car I took it to pep boys and checked the fuses and the fuse for the light was missing, but when I replaced the fuse I found that they had broke the air intake of my s60.

If I could give them a negative I would.
