Untrusted car service an repairs

We took our car in for a service and a new battery. They also had to pump the diesel to the engine. After R14,000 we got the car back. We then realised that the car had no power. We took the car back. Then suddenly they had to replace the turbo and something got stuck in the engine. Now that will probably cost another R30,000. When we got there to tow the car there is another BIG dent at the front right wheel. I won't recommend them for any service to anybody. They are just ***********.
