Rubish service

Pathetic service I was called to come and pick Up my car yesterday , I got here in a hurry because I was told that the is ready... I drove the car and realized that my engine light was still on, I tried getting hold of the consultant who was assisting me by the name of Palesa, I called they said she will was on a call, I left my details with a lady called Zanele or zandile and I still did not get a call back this was around 2 I kept calling Palesa and sent her two emails but she did not get back to me, I than called again and I spoke to Patience Who than assisted me and connected me to a gentlemen by the name of Obry who assisted and told me that I was in a hurry when I came to pick up my car and he didn’t get a chance to advise me on the light, fair enough but my question was why did Palesa say my car is ready if it was not... cause if you tell my car is ready all I’m going expecting to come here make payments and go... so today I came to bring my car in as agreed with obery as I’m driving in this lady by the name of Monica is telling one of their guys that That this is not a walk in service so I asked her does she really think I would just come here without calling I found that really rude and disrespectful if I was coming here without an appointment she has no right to say that what so ever... so I’m just not happy with with this service overall... I will never bring my car back to this dealer ever again... imagine out off everyone that assisted and I spoke to only Obrey and Patience seemed keen to help me and to up after all the calls, Palesa call me back with a hi I got your emails and she called me after 5... so you saying hi I got your emails what about my emails did you do anything about my emails???? In all honesty the service I get from Mercedes Benz and Land Rover Sandton it’s always the best you guys don’t have customer service ..... BAD SERVICE
