Worst Place to buy a car

We bought a BMW *** model from them November 2014. The day we went to go fetch the car on inspection we saw the back light isn't working. The promised us that they will fix it.... A week later we saw that the car was leaking oil bad.... We phoned and they told us at Vereeniging branch were we bough the car that was only the new oil they put into the car..... A few months went past.... We hit a pothole on the way home.... Next day we took it to Vereeniging tyres. On close inspection they saw the the sensors, brakes, brake disc and shocks are damage on the car..... The guy asked us when was this car serviced. When we took the service book we saw that it was done before we got the car... That guy told us it was impossible as they would've picked it up the day they did the service. We went to Durban on vacation. Came back warning lights went on... We had to replace the Valve tronic motor. Took the car for service they told us all the parts we have to replace because it was not done at previous service. the branch closed in vereening and nobody at Randburg is phoning back. These people are hiding stuff..... Bad service. The back light is still not replaced!!!!!!
