Worst service given for a R323 000 Haval

We bought a Haval H6 at the end of June 2019. When my husband took possession of the car, the car had a chip on the windscreen which we were told it was going to be fixed. A few weeks later the 2 old tyres are not changed, one of the doors are malfunctioning, there's no spare key, there's no service booklet. I call and bring all of this to their attention. We are told to bring the car in, which we did. No alternative car is given to my husband. The car was supposed to be there for only a day, but a day after no contact is made with us. Upon calling them i'm told that my query is given to someone else who says that he's busy running around and will only attend to my email in an hours time. Its past an hour and no contact has been made so far
