Bad service

I bought a car with Autoking in Milnerton and after a week it gave problems with overheating and I took it back to them to fix the problem. After they gave it back I had the same problem a week later and it happened two more times and decided to take it to someone else. I also had to beg them to service my car, because they gave me the car without servicing it and the service was due when they had the car. After two months the wiper motor gave in and they are not willing to contribute anything towards the cost. After selling the car they don't care about you anymore.
