Needed closure

Hi my name is TEBOGO,I bought a Bmw 118 Motus select menlyn in February 2022 with finance ,it was a second hand car cost R219000 and took the warranty with m sure,the problem is the car is not even 12 months but it started malfunctioning and I reported the matter with them they said they is nothing they can do I must claim with the warranty to fix my car,I took the to Bmw to get it fixed and the problem was the wiring of the car but m sure refused to pay the said the don't cover wires and reported the matter to Motus select again,but they said they can't cover the cost so now I have to pay R8900 to fix the car that is not even 12 months I even struggle to pay the instalment of the car cos I'm busy fixing the car.
