MFC is selling us cars that have reduced kilometers and they don't even care

I bought a car under GP Combrink financed by MFC and this car has been constantly giving me problems and when I bought the car it was on 70 000 kilometers I when then tried to find out on the car's service history and it came to my surprise that it was last service at 80 000 kilometers. This obviously meant that the Kilometers were reduced, I then spoke to MFC that we were *****ed by GP Combrink but the did nothing the kept my query pending for over two months and after told me they couldn't assist me I have been talking to a gentleman by the name of Mzwandile who did not have the sense of agency I had to call him every day for feed back in this past 2 months, as I'm speaking now I don't have a car and I'm constantly paying MFC and my insurance the car broke down in less than 6 months since I had bought it
