Clio nightmare

Bought a renault clio in October 2020, within days I was complaining about issues I had discovered with the car. Aircon had no gas, radio not working, front tyres worn out and service light was on. Car had no service history book.They refused when I suggested to take the car to Renault for a diagnosis which they still do coz they have a mechanic that checks the cars there yet the issues persisted. No one knows if that's a certified mechanic. I've driven from Middelburg to Meyerton more than 3 times in a period of 2 months at my own costs.They wanted to let me drive the car with those issues claiming they'll find me another car but couldn't put it in writing until I decided to leave the car at the dealership in December when I found myself on the side of the road coz the car had no power, yet "the car has no issues" as they say. I have requested they settle it with the bank because they've been using it since I left it there and they are finding every excuse to do so yet I don't have the car in my possession and still paying for the car.
