MFC CONTRACT NOT COMPREHENSIVELY DISCUSSED WITH ME

Financed a Ford ranger with MFC through Auto pedigree in the vaal. Had to take it back because they **** to me saying it had at least one free service left, did not badget for service because I was told there's still one available only to find that there was none. So I had to take it back because I was now wondering what more did they lie about. They gave me a KIA RIO as per our agreement but MFC seemingly allowed them to make it be a trade-in. Even found out at a later stage that the balloon had now increased. I feel that I was not properly made aware of the terms. The contract was sent to me yes but I need to MFC to prove to me that they made sure that I understood what I got myself into. This can be in a form of the recording where they finalized the deal with me.
