Unhappy client

I bought a car last year Renault Kiger 2022 model .I was then involve in a car accident 14 December 2022 same year. Insurance took care of everything and I got my car back on 15 March 2023. But since I got the car never found peace the battery had to be replace now and then,I am on the 3rd or 4th battery . In the year 2023 I literally have been paying the car installments without enjoying the car. Even now the car has been with Renault ondekkers since September have been traveling with the taxis will only collect it today(02/12/2023) because the day they said it was fix when I arrive to collect, it couldn't move. The lady that is assisting me says the car needed a kick start. I have been calling my insurance spoke to alot of people and sent emails that they should do something about the car cause clearly it is not in a good condition for me to continue driving it. Even though the insurance is taking responsibility of paying the damages but it is not fair for a customer to struggle like this. A full year of 2023 I only drove my car for a while the rest of the days it needed this repair or that. Even now that I have to collect the car I am frustrated and scared wondering how long will I drive before it dies on me.
