Worst experience ever, buying a car.

I recently bought a vehicle from We Buy Cars Johannesburg South for my son. As per the standard rule they had to send the car for the repairs noted on the DEKRA report. From there on things went totally sideways. It took two weeks just to get feedback on the progress of the repairs. Then when we were called to take ownership of the vehicle, we noticed that several items were removed from the vehicle. The VW badge on the tailgate, the lid for the center console inside the vehicle and the passenger sunvisor all items that could be verified on the photos that they had placed on the website that was there. I still paid the full deposit and the manager said they will replace the parts and let us know. More than two weeks went by. I sent email after email, WhatsApp after WhatsApp asking that the manager call me or give me feedback. I received some soppy story from the salesman over WhatsApp. The salesman even sent me a message on WhatsApp telling me that I should rather cancel the sale because he can't find the missing parts or get a place to buy them. I managed to get pricing and availability with one phone call to a VW dealership. I contacted the customer support department, and they called back. Low and behold, the next moment, after a total of three weeks I get an email, not a phone call, an email to say I can come and fetch the car. So, I take ownership of the car and after some more back and forth about insurance documents where they say the bank would not accept the insurance policy as proof in insurance, and when I ask who at the bank so I can contact them, I get told that it is not the bank, they just know from previous experience that the bank will not accept the full policy. Long story short, three weeks and tree days after taking ownership of the car I still don't have my license disc or any proof of NATIS registration. I would rate them 0/10 if I could.
