Barloworld Toyota Centurion selling BAD quality used vehicles

Be very careful when purchasing used vehicles from Barloworld Toyota Centurion as they are only trying to get rid of unwanted stock. I purchased a used Renault Duster from them and after asking them before signing the OTP if the vehicle had ever been in a accident the answer from them was no. As I’m not very clued up with these things I took their word for it only to find out after a couple of weeks that in fact the entire front of the vehicle had been sprayed. I send mails to them asking why this was the case but till today no reply from them. The other issue I have is that when you accelerate the whole car shakes so bad that it feels like something is going to break soon, they send the vehicle for repairs where by the drive shafts were only re-coned and after a while the same issue has returned. My vehicles manufacturers warranty also expired because of work on the vehicle not being done by Renault, after having a meeting with the DP I was advised that they will not pay for any more repairs and that I should rather take my case to the Ombud’s. What shocking service!!!!!
