Mislead into purchasing a accident damage vehicle and being told it's accident free

Mislead into purchasing a vehicle that was previously in an accident but wasn't not told by the dealership. I was told that the vehicle is accident free, Dekra test was done without picking up accident damages I find it disgusting for a well know dealership to mislead customers into purchasing a vehicle. Pictures have been taken and sent to Lindsey Saker Midrand yet I didn't not get any joy from the staff and the manager! It seems as if they take the youth for a joy ride !!! If I wanted to purchase a accident damage vehicle I would have went to a SMD not VW .. Pathetic Customer service !
