Very disappointing customer service

I took my car to Mercedes Bryanston to have my breaks fixed They offered to fetch me from work and called to say they were on their way. I waited outside and after 40min I called the dealership and was told that the driver was still on his way. After an hour I ordered an Uber to get to the dealership as the driver had still not arrived. When I got to the dealership I was asked by my advisor to not give him a bad rating just because the driver hadnt shown up (trivialising my discomfort).<br> After this someone bumped my car and the fog light popped out (undamaged). I called the dealership trying to book an appointment and the girl hung up the phone on me. I called back and was told to leave my number and that someone would get back to me. No-one did. I called back again the next day and made an appointment. When I dropped my car off no refreshments were offered. They billed me R650 for fitting the undamaged fog light. I had an accident with my Volvo where Volvo re-fitted my bumper for me free of charge. I called customer servie for advice on the matter and was told that its not their policy to interven with dealership matters. R10 was also ****** out of my vehicle
