POOR SERVICE AT MERCEDES UMHLANGA

it is so sad for me that I drive such an expensive and reputable car but have experienced the worst service ever. I have been driving and servicing my cars since 1997 and never have I been treated this badly. there is nothing wrong with my CLA200 bought in Pinetown 2021, I enjoy it. It is the service at Umhlanga that I have problem with. I booked my car in for service I could only get a Friday (12 January 2024) booking which was okay, left the car at 07h30 in the morning and was given transport back to work. My service man was Sipho. At about 15:00 I found it strange that no one had called me to tell me how the service was going. I called Mercedes several times and there was no answer. I waited at work until about 18:00, then hired a car to get me home. I phoned on Saturday and they said the Service dept is closed on weekends. I called on Monday and someone from Mercedes came to fetch me only around 12:00. My whole weekend and Monday were already spoiled. I then logged a complaint with their customer liason officer, in person and on an email. The reply was we apologise, we will investigate and get back to you Today 18 July 2024 they still haven't told me what happened. Since then I have had problems with my front left tyre. I went to check it several times until someone told me that my rim my cracked. I was shocked. I then took to someone to repair it yesterday only to be told that my rim was welded before and it three cracks. In my entire life I have never taken my car for a mag repair/welding. The only place I have taken my car so far is for tyre change of my rear tyres and I was there to watch the process as I am always curious. This only leaves Umhlanga and I am really angry right now because when you look at that one mag and the other it is too old for a three year old car. Only at Umhlanga did they have enough time to change my mag to an old one. Only there could someone have the knowledge of setting the sensor such that I don't see anything wrong with it. The fact that they did not get back to me with the results of the investigation on the complaint I filed the first time, tells me there is either something quite ***** that is happening there or their service is so poor that they can't even help me with a formal complaint lodged or they felt that I am not important enough to waste their time on. i am appalled. I wish I never bought this car. If I could I would change it but my finances do not allow me. Times are really tough and I cannot really make a decision like that but I am stuck with them because they are the only ones in Durban - it is frustrating!
