Freehold Hyundai unlicensed tech wrecks my car receies 2 tickets Freehold, New Jersey

 August 3.2011 I brought my car to the dealer for a simple repair.  The car was to be ready at 2pm I called at 3pm the receptionist was rude and nasty told car not ready. The service guy called at 4pm said car just going in.  I then received a call around 4:45 .my car was in accident. The service people very evasive and not giving any information. They have been difficult, and there have been 2 appraisals on the car both over $6,000.00.  I have concerns about safety and depreciation of my vehicle.  I got the police report and found tech had a suspended license and was ticketed for that and also careless driving.  I do not want the car back and feel they should replace my vehicle under these circumstances.  They have treated me like this was my fault go figure!!!
