Refuse for your car to be repaired at Riverside autobody in Kyalami

I dropped off my car in February 2024 and to date u still don't have my car. They don't communicate, you have to call to get a so-called update. I have complained numerous times. Even complained to my insurance company nothing is happening, still don't have my car. I honestly believe that they take on too much and don't have capacity, my car was supposed to take less than 4 weeks to repair the hail damage but it's taken 12 weeks and counting. I am totally at my wits end. The service is totally disgusting.
