Worst buying experience

I bought my car from Motus Renault Roodepoort in January 2023. I was promised by the then Dealer Principal, Denzel that I will have my new license disk by the 1st week of February 2023. I continuously follow up with him by when I will get my disk, it was always we need another week. Eventually he stopped making contact with me. In October 2023 I still did not receive my new disk & the disk was expiring. I went to renew it myself, only to find out that the vehicle was not registered in my name, it was not even in the dealerships name, it was still in the original owners name. I personally went to the dealership to find out that Denzel no longer works there & I started to deal with Vishal, the new DP. I was told the dealership lost the Natis document, but it will be resolved quickly. Since October 2023 I have to obtain a temp permit & I need to remind Vishal when its due, most of the time I had to drive there to fetch it was it was expiring on that day. As of today, 28 February 2024, I still don't have my disk. Feedback is that they cannot get hold of the original owner to request a copy of the Natis. This is the worst car buying experience I've ever had in my life & I will NEVER buy anything from this dealership again !
