Hyundai Newton Park Port Elizabeth

I purchased a second hand vehicle from Hyundai Newton Park Port Elizabeth. Yes I was a single middle aged lady buying a vehicle on her own. First mistake. Second mistake, I am too trusting. On buying the vehicle i asked if it had been in any accidents and was informed that it had not. A few weeks back someone ran a stop street and as much as i tried to avoid hitting them i just clipped the rear of their vehicle. On sorting quote for repairs to my vehicle i was informed that the vehicle i bought from Hyundai was in an accident previously. On top of the my mechanic who serviced my vehicle tells me there are various clips and connections broken on the engine or missing. He says it is definitely not right. OK so I go to Hyundai 4 weeks ago, have phoned repeatedly, still no feedback. they waiting for records apparently. The manager who helped me never called me back and has now left the company. All I want is some answers please. I think I am going to a reputable dealer as I will not get hoodwinked. In hindsight I am not so sure. But sale has been made and that is all they care about. All I can say is be careful ladies....
