HORRIBLE SERVICE AT MBOMBELA HYNDAI SERVICE CENTRE

I took my car for service on brakes and a left side rear door that cannot open anymore. After they were done I fetched my car same day. Since it was very late I didn't notice any foul play beside the brakes that sounded badly when I brake. Since I was with my son I didn't even notice that beside the rear door that was not fixed, the driver's door was also affected. Only God knows wha was done to my car because besides the doors issue, that belt which surounds the door frame is torn in the middle, there are hole marks on the bottom side which were not there. The steering wheel shakes accompanied by a funny sound when I apply brakes. I don't even feel safe driving that car anymore. I was called to check how their service went and I explained everything. Instead of helping they accused of having involved the car in an accident, which was to me an insult and a serious allegation. The car can be checked inside out using the best technology that may be there. Bottom line: it had never been in any accident since I purchased it in 2016. I regret ever taking my car to those people that day because it wasn't the first time they had issues with my car. So because they knew its service plan is expiring they deliberately tried to destroy it to get even with me. There's a lady there who pull strings with almost all the Africans that bring their cars there. On that day she was at loggerheads with a guy whom she left puzzled whilst he was still trying to express himself over something regarding his car. The man was so furious and demanded to be given his car keys and leave. I wonder what went wrong with that woman because she once came to me to apologise from nowhere after I just arrived for a service there. I thought she changed via introspection, but this time around her demon was back. She didn't even greet me but passed a number of times where I was sitting. I thus thought that this was influenced by my presence as the other guy was also having issues with her. No one could believe my car was turning five years due to how comfortable it was. All that is gone just within the blink of an eye. I'm deeply hurt, I need justice to prevail in this matter. I also feel I can take it to the media sothat other people may come out and voice out their pain sothat the whole world may know what other people unnecessarily go through. My car is a Hyndai Tucson 2016 model (elite). I adore my car and am so heartbroken. I heard never seek help from my insurance company to prove that I took good care of it, Please help..
