Beware webuycars

I bought a Porsche from the Siverlakes branch on 28 Nov. It was sent with courier to me in George. However, no documents were included. Since it arrived here i phoned/whatsapp every second day and asked for these so that i can register the car. By law it must happen in 21 days. Nothing. I gave them various post/courier options. To this day, 35 days after purchase i still can not drive the car as it is nor registered. I have now payed myself for a courier to collect, but i am not sure if they will be handed the correct Natis and ownershio papers. The salesman and managr that i have spoken to on various occasions do not go further than blaming it on someone else. Nobody cares to just finish the deal. Pathetic!
