Lazarus Motors Ford

My car, insured with Discovery was in an accident on the 17th April. After the body work, it has been with Lazarus Motors Ford since 23rd June for some mechanical repairs. I went to make a follow-up at the end of July and Ms Ronelle Brits said they are waiting on parts, she cant tell me nor estimate when they will get the them, and will get them when they do. Also said my car is not the only vehicle they are fixing. I am now in the middle of month 5 without a vehicle, and i am an essential services provider. I am VERY FRUSTRATED, with no update whatsoever.
