Overcharged by Mercedes Benz Constantia Kloof

Horrible service, lack of accountability and an attempt to charge me for items not rendered or required!! Worst 3 weeks ever! My car was at Merc Constantia Kloof with an apparent laundry list of issues, I was overcharged, I was charged for items not related to the identified error and I was charged for work not done. When I confronted the Dealer principal, he said: "the invoicing clerk didn't understand the job and misquoted". How do you blame the clerk instead of taking accountability?? Especially because the client had queried the quote with the Service Manager and Workshop Manager, and neither one of them noted the errors until, I, the client noted their overcharged items per advise from another dealership. The quote was inflated by almost R50 000!! Needless to say, I will never use that dealership again. I hope Motus South Africa knows that this is how Nic* & D*ve are treating their customers.
