Pathetic Service

Pathetic service at Mercedes Benz Centurion

We booked our car for repairs on tuesday(13/02/2024) as it was flashing the engine light.The service agent by the name of Karen was rude and gave us an attitude and right there told us the car won't be ready same day,which we did not have a problem with.....She later calls to say they going to drive the car around to investigate and we allowed them.The following day;she calls to say the car is ready,it was nothing major (mind you the car is popping engine light but according to her is nothing major)and they swapped the valves around reportedly.So technically no repairs were done on the car.We collected the car unsatisfied as we were and the car was making some weird sounds on the way,even the following day it was still making the sound. We called in and were told to return the car,"however if there was something wrong their guys would have picked it up",which maintained that they actually did not repair the engine issue.Guess what,the morning as we returning the car,the engine light still flashing and the engine is actually shaking.Upon arrival at the dealership,the same Karen said they cannot repair what they cannot see,which still confirms nothing was done to the car on tuesday/wednesday. Yet the car engine is shaking and the light is popping.We are very disappointed in such a service from a dealership of their magnitude. And the fact that they as a dealership together with their mechanic downplay the issue makes us furious. There is absolutely no way a car can flash an engine light and its nothing. The level of incompetency and unprofessionalism is appalling.
