Took my 2014 Mercedes C250 Bluetec in for a service and they completely destroyed the car

Took my 2014 Mercedes C250 Bluetec in for a service and they completely destroyed the car. As soon as I drove it home and parked it the car started leaking oil everywhere and the coolant reservoir exploded. When I picked up the car I was told they didn’t have the tools to do any of the other work and that they had 2 apprentices working on vehicles while the one qualified mechanic was working reception and supervising. It cost me $4500 at a reputable European mechanic to fix their damage. I think this place changed staff or owners because my initial service there a few years ago was fine. Take your European cars elsewhere.
