Atrocious Service- worst I've ever experienced in my life.

Atrocious service. Totally disgusted with their level of service. Took my car in for service in March 2020, in November 2020 I have to run around Sindi and Pier to resolve issues from the original service. Sindi the service consultant was extremely rude, arrogant, banged her hands on the table while she spoke to me. Pier the manager said he will call me back to book the vehicle in again, he didn't. How do you treat people like this and get away with it? Your reviews on Google Maps are terrible, how does management turn a blind eye to such?
