BAD SERVICE

I serviced my car with Car Service City (MIDRAND)last month and they broke something in the engine and then when I fetched the car, they never said anything to me. They instead kept quiet and never reported this to me. The car is now giving me problems since this last service I did with them. This was my second chance doing service with them because first time they didnt stamp the book , I was actually giving them a second chance but they did something again!!!!!!!!!!!!!
