Mercedes Benz South Africa Customer Service non existent

I purchased a W205 C250 from Century City Orbit Motors in 2015 and have been complaining about the vehicles performance for the last three years. The dealer in Century City as well as their head office, MBSA, in Pretoria, refused to acknowledge the problem or test the vehicle and wrote it off as a characteristic of the model. Because the performance was a great concern and knowing that there was a problem as I previously owned three previous C Class models in a 16 year period, I requested the assistance of the Ombudsman. These puppets just agreed with the comments of MBSA and also wrote my problem off. Now four years later, out of frustration and even though the vehicle is still within warranty, which was my concern, I had a four wheel alignment done by Supa Quick in Bellville and the problem disappeared. I felt that it was the responsibility of Mercedes Benz to have at least tried to resolve my complaint. This will definitely be my last brand of Mercedes vehicle as their customer service is one of the worst in the industry.
