I bought a Volvo from a used car lot on October 31, 2012. At signing, a due bill was written and signed by the dealership stating that they would fix some problems that I noticed. The first time the dealership took the car to be fixed, they had it for four days and none of the problems were fixed. Also, there we more problems with the car when it came back. It took four months for them to take the car again to get these problems fixed. They have had the car for five days now, and the dealership is hanging up on me and ignoring my calls. When I bought the car the airbag light was on. Later I found out the the airbag was faulty and needed to be replaced. Is the dealership breaking any laws? I have no idea what I can do.
