Financing a broken car

I have a problem, I had finance a car (Ford Ranger) with MFC, through Autocity Nigel, the Salesman was Lucelle and Manager being Tommy, I've been paying for the car since 14 March 2023, some of the things which were not disclosed to me was that the car was repaired somewhere else before they put out on their market for financing, I only drove the car for one month, and eversince then the car is stuck at a workshop in Pietermaritzburg, because I was also told after that the car has a repaired gearbox which was done in boksburg, of which the company doesn't have sub branches, I'm here now stuck with the situation and I'd advise anyone to not fall for the trap I fell for.
