Car dealership

My case with BNA motors was handled by MIOSA. The case was closed by Hilda Tau before I received the car. I emailed three days after I received the car to reopen the case because the car broke after three days.. I was given a number to contact NCC.. uptil today I heard nothing from NCC. Mfc nedbank told me after 3 days of having the car that the only people that can solve this problem is miosa.. So uptil today 11 months later.. I'm paying MFC. but still don't have a car.. As a pensioner.. Where can I get help. Or who can assist.. Because I got no help from Bna motors, miosa. Nedbank or NCC.
