Mercedes-Benz Midrand Poor service

Mercedes-Benz Midrand has the worst service ever.. From their receptionist at the door to their service department which never ever answers the phones or is not available when you go on foot. I went there 3-times for assistance. My car has been displaying an alert that it needs a b8 service and I don't know what that is so I went to Mercedes-Benz Midrand as it is the closest to me to enquire about what a b8 service was and how much it would cost. On the first day, Saturday, I was told the service team does not work weekends, which is fine but had they answered my numerous calls I would have known this. Second day, all service personnel were busy, third day, the receptionist was eating niknaks by the service desk and I was told to wait from 15:45 to 5 0clock. I went again to the receptionist and she said I must go to the receptionist from the service department after an hour waiting...never again. It is worth mentioning that the lady at the tea bar tried by all means to get someone to assist me at the service department, but the two guys there had their hands in their pockets and said the is only one service guy and I must wait..I have just left and not going back...
