Mercedes Benz Sucks - Once they have your money you are on your own!

Had to order some parts for my E 350 Coupe from Sandton Mercedes prior to booking a service. Was told the parts would take two weeks, then got told they would be 4 - 6 weeks and now they cannot give me an answer as to when parts would get here. Escalated to the dealer principle and still waiting for the courtesy of a reply. Buyers beware Mercedes is one of the very worst customer focused companies in my opinion. Buying a Mercedes after years of fantastic Audi support and service was the biggest mistake I have ever made. Mercedes take your money and then drop you like a hot potato. The arrogance oozes from every orifice and don'e even try to escalate to the MD as he doesn't give a damn and will NEVER reply! He lives the good live in SA but couldn't care any less about his clients!
