CAR BOUGHT BUT THE PROBLEMS REMAIN

I bought my Peogeot 207 GTI at Fourways Peogeot about 3 months ago. After about 1 month, I discovered problems and sent it in for repairs. Then Peogeot reckoned I did modifications on the car (which I didn't) and then they wanted me to pay for the repairs of R 22 000. When I bought the car, they said the car was in for all the inspection tests and the car was 100% according to them. After a fight with them they realised that it was their mistake and didn't notice it before they sold me the car. They then fixed the car, after almost 2 months of waiting. Every time I called to know how's the car doing and what's happening, the person (Phillip) puts the phone down. Finally when I got my car back, it wasn't even a week then the turbo didn't work at all and lights were coming on saying \oil pressure to low". This is really very bad service from Peogeot"
