Defective vehicle/poor after sales service

Purchased a Polo Vivo GT from them. I reported all faults once delivery was taken. The car was taken back and they sorted out two of the faults. I was told that everything else was fine. I continued driving the vehicle with the existing faults for about 4/5 months and the issues just got worse.I took the car for a private evaluation and the report was given to Pinetown cars. They refused to repair. They say that it is wear and tear, even though the issues were initially reported a week after purchase. Numerous emails have been sent to them, but the manager and DP just ignore the correspondence. They claim to have sent the car for a c.o.r test, but I have not been given a copy of that test to date. Shane, the manager was informed by me that I would take the issue higher and place a review on "hellopeter", but I assume that he doesn't really care as I was ignored once again.
