If you value your car, NEVER TAKE IT MERCEDES-BENZ CONSTATIA KLOOF!! they will damage it!!!

I have never in my life experienced such poor service. Our car's key stop functioning. We took our car in to Mercedes-Benz Constantia Kloof. We told them the key is ot working and that we brought all the necessary paper with. Nigel told us that they don't need the papers. It took a month for them to request all the documents from us before they even bothered ordering the new key. We requested a loan car and was informed that they no longer supply loan cars. After a month they called us to say that they had received the incorrect key and we must please come get a loan car while they wait for the correct key! (AFTER BEEN TOLD THEY DON'T SUPPLY LOAN CARS) They even apologized for the state of the loan car as they just got it back from another client. In otherwords they **** to us outright up front. But this is not the worst. We went to college the car and were in a hurry as I had to teach a class 10 minutes after finally getting the car. We get home and the driver's side seat is ripped!!! There was no mention from Nigel about the damage. We immediately called Nigel and he apologized and said we must please send an email with a photo and Mercedes will arrange for the seat to be repaired. It is now 3 week later after sending the email. We called Nigel to ask what is going on. He says he didn't get the email. We emailed it again and called 30 minutes later to ask if he actually received it this time. Nigel said he did, but now management has to first decide what to do!!!!
