Mfc Vihlce Finance

2020 February I bought Hyundai i20 at Auto Unique car dealership, the car was on 94km,through MFC financed. Same month the car started giving me problems, I took it back to the Auto Unique Pretoria, they started making appointments, when I must bring it. Every time when I take it there they would say stories, postponing until there was a national lock down,around August they open,meanwhile I wrote a complaint letter to MFC, they didn't wonna hear, they told me I must go back to the dealer which did not help me, my car broke down, I fix it myself, now the car broke down again, oil failed, its engine down. I warranty of Impact say they will only cover 15000 while the car nedd 35000 to be fix, short fall of 20000 is on me, am tired of fixing the car, while I have to pay installment, it's within 1year the car is giving me problem, the garage won't help me and also MFC, now I have to pay for the car for 5years, which is not useful to me, the car is at the workshop of impact warranty, cause I don't have 20000 to pay for it, I wanted to trade it in but I was advices I have to wait until I Done atleast 1year with it. I called MFC explaining what is happened they told me they will pick up the car the way it is, now I don't know what to do
