Terrible service from Renault Motus East Rand

We purchased a brand new triber dynamique 2022 from Renault Motus East Rand and we took delivery on the 29/03/2022 and today is the 29/04/2022, it's one month later and we haven't recieved our number plates and license disc, the temporary ones have expired and the dealership is well aware of that, It is ******* for us to drive around with an expired license plate. I'm not sure what is the hold up with the license plate and disc, Widney was the sales representative, however once the sale was concluded, he stopped taking our calls, his service and communication skills is pathetic, He drove the car down to durban without notifying us, I assumed he was going to have it brought down on a truck. Only when he got here he tells us, the truck is too expensive. He delivered the car with a chipped windscreen which is still not sorted. We then spoke to the sales manager Jabu Radebe who assured us he would have everything resolved by this week, but still nothing. Both the stub axels are rusty which I cannot understand because this is apparently a brand new car. The car makes a squeaky noise when reversing. The radio sometimes go off and on suddenly. We need this resolved asap, we cannot be paying so much for a brand new car which is already rusty. Surely no one wants their brand new car to be delivered to them in this condition.
