Mercedes Benz Sandton loses quality service to its Customers.

I took in my vehicle to attend to the front lights. When I went to collect the vehicle, the aircon unit in the back seat was lying loose on the floor. The service advisor roughly attached it back and hurriedly left me alone. I had to follow him to tell him that the thing he just attached waa still not okay as the louvres were still twisted. The car was moved from the collection bay back to the workshop where a mechanic was asked to fix the aircon. A week later I called back to register my complaint with the Dealer Principal who was not available. A workshop manager tendered his appology about the whole thing and the fact that no one called me to findout if everthing was okay, which is standard practice with sister dealerships. To date I have not received any phone call from them.
