Traded in vehicle not settled after a month

I traded in my car at Motus Alberton 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 has expired today 14 August 2025 and still no word on the new registration. I am completely disappointed at the service I've received and would like these issues to be sorted out as soon as possible.
