Not Helpful

I've traded in a car of mine a few months ago and the car went for,i had to take back to the dealership Motordeal Nissan Vereening,because there was faults on the car. I took another car and that car had oil leak after oil leak after taking it back numerous times. Eventually i was given another car,only to find out that the car's bonnet,bumper and door was replaced and the dealership did not inform me about it. I found out when i took the car to another dealership to trade it in. I spoke to representatives of MFC,that work the vereening area and they said i must send my story to the MFC COMPLAINTS department,because they can assist me,because the dealership where i got the car gives me the run around like crazy....only to find i'm getting the same treatment from the Finance house. I'm sitting with a car,that i must pay over 72 months and the car has faults which the dealership never inform me about....Who can help me please?? I DON'T WANT THAT CAR ANYMORE,I WANT TO CANCEL MY CONTRACT ON THAT CAR!!!
