Poor service from SANDTON Mercedes Benz.

This is for MERCEDES BENZ SANDTON. I took my car in for a normal service on the 25th May 2022. Upon collection of my car on the 26th May 2022, I discovered my sunroof mechanism was damaged and returned my car immediately. Fast track forward, 10 days later I still don't have my car back from Mercedes Benz Sandton. I'm left stranded without even a courtesy vehicle to help me get around. I'm having to follow up on my own, without even a call from them. The dealership damaged the dintoof mechanism and now I am inconvenienced. This is a lack of client service and professional conduct. Utterly unacceptable.
