WORST SERVICE EVER

Good day I jus wish there was a rating below 1 Graaff brakes centurion doesn't even deserve a 1. After getting my car 8 days later from 4 hrs I was promised. Yesterday Friday the 19th of Dec I got back my car with an engine light that wasn't there before, the car us now stalling when I'm driving and losing power when I sent them a mes that my car is not ok the answer I got was "we only do brakes " bt I have evidence all messages showing the reason the car was kept by GBrakes for 8 days is because from day one they did something wrong and they started the blame game from something being wrong with my ABS, next thing my booster has a problem n was taken to midrand for rectilinear, nxt thing my car is not moving from park to my battrey being old. These pple hv messed my car and I work with it now it's parked at home I can't even drive it. The brake pedal has been loose . In short it all started with changing rear brake pads to a car I can't drive anymore after keeping my car for 8day. I really need help I'm a woman with a condition I just think Graaff brakes is taking advantage of me. Any advise all proof I hv it
