Traded in Vehicle still not settled after a month

I traded in my car at Motus Alberton Renault multifranchise on 8 July 2025, I was told they would be settling the previous car with my financer in a few days. It's been over a month and my previous vehicle has still not been settled and the car is no longer in my possession, my new finance for my new vehicle has taken effect, I keep being told there are delays with the accountant working there and now I am concerned that I will be debited for two vehicles come month end, I have tried being patient but this has simply been dragging on for too long, and I'm not receiving any update as to what the delay is. On top of that the registration for my new vehicle has still not been finalized, first permit expired and they gave me a new one, now this one expired 14 August 2025 and I got another permit. Today is the 20th of August and the settlement still has not been done, I got debited in July for the previous car traded in and was told they would refund me but still nothing, Now I am afraid I will get debited again on the 25th for both vehicles, the traded in Kwid and the new Kiger if this matter is not resolved urgently. Yesterday I got told the reason for the delay with registration is because the car needs to get a Road worthy test done, cause the previous one expired, so I have been driving a car that isn't Road worthy and was not told, if I had not followed up I wouldn't have known. This whole deal was done dishonestly and I am seriously considering canceling the whole deal. I am completely disappointed at the service I've received and would like these issues to be sorted out as soon as possible.
