poor dealership, thieves

I purchased a car from them and it was a mistake. They sold me damaged vehicle, I heard their advertisement on TV and radio and they seemed to be reliable but they were not. After I discovered all damages I returned car back and they promised me to cancel our contract and to send me a refund. It was about two month ago and since that time I never heard from them and I haven't received money yet. They ignore all my tries to contact them. Beware and better stay away from this company:
