Unfair treatment

I bought a car from Audi Polokwane and last year when they deliver it to me February i noticed that there's few things that are not right so the sale man said to me he will attended them so there was lock down i couldn't take the car to them by that time then i took it back to them so when i was on my way back JHB i hear the sound that they said its resolved was back so i reported it again but nothing was done so this year got a breakdown the car was delivered to Sandton Audi they fixed the problem so my warrant only going to pay 8k and i need to pay 30k so when i ask Audi Polokwane to assist paying for that car as they knew about the issues before the car breakdown they refused to pay even when i ask them to meet me half way still they don't want to assist they even said i need to come to them by Polokwane to understand my deal with them but my question is how as i don't have a car for almost 5 month and i am paying my installment for that car every month but not seeing the value of my money
