Haval Milnerton service is the worst.

I went to test drive a car last week Thursday. I then waited an hour for them to decide if they are selling it to me or not. Apparently 2 of us through 2 different sales people rocked up to buy the car. I was dealing with Robin, I think. Anyway I bought the car and paid cash for it. When I spoke to the Financial Manager, Damien, he said it wont take long to get the paper word done. Well over a week now and I still don't have the paperwork and so I can't drive the car. I have called and messaged the sales person who always comes up with some excuse. First it month end, then he fell and hurt his leg. What next? When I call reception to speak to the manager, I get put through to a number that doesn't exist. I just want the paperwork done so that I can get on with my life and drive the car. It was a simple cash sale. Not a higher purchase sale. I am pulling out my hair over this. I live in the Southern Suburbs and not easy to just drive to Milnerton. I need this resolved ASAP. Please people avoid Haval Milnerton. Their service sucks.
