Cloned vehicle

I bought a car from a dealership with the help of finance from Wesbank in Jan 2013. when i tried to renew my license disk in 2014, i was told that the car was registered in someone else's name. i reported the matter with the police, an investigation that took 6 months was done and the car was cleared by the traffic department. i was told to take the clearance certificate to Wesbank so they could facilitate the renewal of my disk. at wesbank, i was told that they could not register the car immediately, they need to do an investigation. this was last year in June. to this day i still have not gotten feedback from Wesbank. i pay my account monthly. i drive around with a vehicle that has no valid license disk and this is a nightmare especially when i am pull over by police. i can not sell the car as it is not registered in my name, i am stuck with it. i can not travel freely in this vehicle so i want Wesbank to take it back and provide me with a car that does not have these issues. it is my belief that this it is their responsibility to sort this issue out as i am their client.
