Terrible service

Very bad service. My car went in for the removal of a catalytic converter and it came back from the workshop with engine cooling issues. They created more problems. They replaced heater valves and fan switches that they were not supposed to replace. I had to book the car in at Audi Rivonia and they picked up that an old used part******* valve/fan switch) was fitted to my car. This is the same part they replaced. Audi Rivonia also picked up that when Flora Auto Clinic removed the catalytic converter, they also messed up the oxygen sensor, now the car has a persistent “check engine light”. I’ll have to get a new sensor because this job was carried out by clueless amateurs. If one goes back to the same shop multiple times to get the same issue fixed means that the workshop is terrible. Never again. Total waste of money.
