Terrible service

My car was taken in for a service and overhaul on engine. My pistons were faulty and repairs were done. The payment was done on Sat 23 Sept 2017. They sent us back to bank despite us having a proof of payment. They wanted it on a certain format. The vehicle was not driving as prior to the service. I didnt think much of it because the engine was worked on. My husband soon also discovered the same and more. He tool the car back to them on Friday 29 Sept 2017. Where he asked them to cgeck the car out. Mario explained it's the barring my husband told them they must replace it because it was not in that condition before the service. They refused. My husband pointed out other faults like the internal cover of the bonnet that is cracked and the headlight water sprayers that protrude when the wipers are activated and the right one does return back automarically. The branch manager George Napier chased him from the repairshop. At the time there was another cluent of theirs angry because of his car. The engine light switched on and I returned the car back on Monday. I ecplained to George the problems and he explained that they will not be assisting us. He had his staff member Mario drive my car and come back and tell me the car is driving right. I am very disappointed after the amount of money spent one would expect excellent service but the car is worse off as before the service. The engine light is still on. I have reported the matter to my lawyers and to the motor vehicle Ombudsman of SA. According to the Consumer Protection Act Sec 54 & 55 confirms that we were poor treated and our vehicle must be properly repaired.
