Dishonestly selling vehicles without natis

I do not recommend purchasing at this action and will never do so again. After buying a car in this place and was told I would receive my natis a week later, its been SIX (6) weeks and I get excuses that the seller has not delivered the natis documents, and that’s only when im lucky to get a response. Natis collection, transfer and registration does not take over 2 days. If the vehicle is sold without natis or there would be a delay, it is the duty of the auctioneer to inform the consumers. The car is fully repaired and refurbished but cannot drive with an expired disc, cannot instal tracker and cannot insure with reasons only known to them. The level of dishonesty, disrespect, and mistreatment which I felt was somehow further fuelled, especially by how im been ignored and screen whilst Im sitting with a car I fully paid for, speaks volumes against customer centricity and consumer esteem. The only way this will end is with a court order and with them delivering the natis and legal costs.
