Very Frustrated Customer

My whole experience started just over a month ago. I went to test drive a 2013 Polo Vivo Maxx with 30000kms on it. Everything at that point seemed fine and I was happy. I arrived to sign for the car and it was still in the wash. After I handed over my traded in car and took my new car home, I got off the highway and noticed a whirring noise when the AC was on, also when traveling over bumps/rough tarmac there was a knocking noise on the front right suspension. At this point I was dealing with both Gerald and Fanie. The car was sent to VW for two weeks(a lot was replaced) and came back exactly the same, only the wheel alignment was worse. I mailed the dealer principle(Keith) twice and had no feedback. The car was then looked at by their service manager(Previous VW Employee) who immediately picked up both noises and was confident they were a problem. The car is still at VW, communication has been almost non existent, getting hold of anyone to get an update seems impossible and my first installment is almost due and I have nothing to show for it. I have also spent a lot of money on petrol for car's to be transported everywhere.
