MERCEDEZ-BENZ Northcliff - Poor service delivery

It is with great disappointment that I have to report on the most negative customer experience I have had at Mercedez-Benz, Northcliff. I took my vehicle in for the change of 4 tires. I waited 45 minutes, (from 06:30-07:15) in the morning) before a driver was assigned to me to deliver me to my work. There was no communication provided to me on why I had to wait so long, or why there were no drivers available when the dealership opens at 06:30 in the morning to service vehicles delivered. In addition, I received a call from the dealership at 14:00 on Thursday, 3 March 2016, requesting the time for my collection. I indicated to them that I will be ready for pick-up at 15:00, waiting outside Gate 1 of my employer. I phoned Mercedez-Benz, Northcliff two times to enquire why the driver was late to pick me up. The dealership contacted me twice as well to inform me that the driver is on his way. Eventually, I waited 40 minutes for the driver, but decided to rather travel with a colleague to the dealership as I could not wait any longer in the burning sun. The service manager, Cassim, apologised, but provided no solution, which further disappointed me.
