Extremely worst service

My wife’s car had an accident in March , I’ve reported it and they just don’t care about having my car fixed , I’ve spoken to numerous staff , even the supervisor, Thandeka on the 15th April and she as well has failed to call me back as she promised to do so. I called again on the 14th May , spoke to Yolanda who claimed to say I’ll help you, I sent her my quotation as she will submit, she failed as well, I called this week spoke to Lebo , sent her my quotation, and I’m still waiting, i must really say this is the worst service I’ve ever received , the car is parked with the repair center and not sure what to do, my wife has been using public transport and what an inconvenience
