NMI Ford Unprofessional Service Department

We have received a quotation to fix our car at R 20,921.39 from NMI Ford Pietermaritzburg. I am not accepting this bill. My car's gearbox was recalled, and Ford Pmb kept quiet. Eventually, the part broke, and Ford had to fix it. When we received the car back after 9 months, it came with a whole new set of problems. Engine misfire – coil packs. No cold air from conditioner. Fan motor assembly damaged. Discharge Hose for the air conditioner A car standing for months, especially outside, while waiting for repairs to be carried out or being damaged during work can cause every single one of these items above.They returned our car after 278 days with all these additional issues and expect us to pay for this!
