Amg E200 merc. Sloppy work and receptionist from hell.

I took my Mercedes to renew it Sandton on the advice of my insurer. An e class amg.. the car had been numbed at the back. Insurance paid out . The car was returned to me.. after some few days I realized the color of the bumber and the rest of the car was not the same and that the review camera was looking funny. So I took it to kwit fit for an opinion. They said the car had not been done properly and had not been glossed.. whatever that meant.. took it to back renew it . Booked the thing signs the papers. Then I had to wait for an hour to be returned to my office as promised by them.. any way when the the driver finally came back for the trip.. a lady called Rebecca at the reception decided that I should wait and someone else be taken to their place instead. Now I had no choice but to return with my car that had writings on the wind screen.. given that they had promised to fetch the car at my premises on two occasions and neglected to do so. .. thanks to this Rebecca reception.. she is a receptionist from hell..so now I am looking for another merc dealership that will have better customer service and will do the job right the first time around.. .. so now I have to be inconvenienced for their slalom job.. infact left me call my insurer. This is irritating..
