Imperial Edenvale are croocks

i bought a used car on the 30 April 15 at Imperial Edenvale, the following day there was leakage underneath. I called the dealership and was told to bring it in at the workshop,wrote an email with problems with the car, after 2days i was told its ready for collection. a week later i was told the car needs to come for major service & dealership said the car is fine. Later ford called to say there are still leakages on the car and cam belt needs to be replaced,called the dealership and i was told i need to bring it back in again. Its been 5 days now and i still don't have a car & even i sent emails to the manager he never comes back to me. They called to say its ready but i was in a meeting when their driver sent me a pls call, called him back & he said someone will come fetch me coz his busy. I have called ans sent several emails but no one responds instead they hang up on me. I was later told they are doing me a favor for fetching me and was made to driver a car with an expired permit. The sales man who sold the car also ignores my calls and they give a run around when i ask for the inspection sheet of the car. I am frustrated because i am paying for a car i don't have .
