Bad service

I booked my MG Zs luxury for a service, then was advices to bring it between 7am_8am My car was still not attended to at 15h00 as it has a dashboard camera I had to call in first to complain What is the point of making a booking and bringing a car in at 8 only for it to be attended after 3pm. I knock off and still have to wait for my car Not prioritized Their number 0124705999
