Caution when purchasing or servicing vehicle at Mercedes-Benz Sandton

I purchased a new 2022 Mercedes Benz C220D, what started off as a great service experience turned into a horrible overall experience. On the very first day we experienced problems with the vehicles sunroof not closing and after a few days the engine light indicated that there was a problem with the engine. We took the car back and the service consultant at Mercedes Benz they assured us it's a small problem and that it would be rectified. After they informed us, the vehicle was repaired and ready for collection we once again were assured that the vehicle was repaired and that we would not experience any further issues with the vehicle. The very next day the same issue persisted and I took the vehicle back to them. The service consultant refused to meet with me and I was confronted by two gentlemen who were trying to manipulate and shift blame on to us to the extend of denying me my right to return the defected vehicle that they sold to me. I caution anyone who does business with Mercedes Benz Sandton (Sandown Motor Holdings (PTY) LTD.) to be vigilant.
