Mercedes Benz pathetic service.

I own a C63 Coupe. I have a cracked windscreen and there is not one windscreen for my car in South Africa. 15-21 days to import. Furthermore my rear rim was cracked due to a pothole. There is not a rim in South Africa and even worse, no rim available from Germany. There is thousands of C63`s in South Africa and even more so over the world. Since I could not get answers from the incompotent people at Mercedes Benz East Rand, I contacted MB South Africa Head office. Since 2nd February 2023 even they did not reply with a solution. Today I laid a complaint at MB Germany with the hope of getting answers.
