NEVER TRUST WE BUY CARS SALES

I bought a Reanult Kwid last year 09/01/2023 from your Randburg store, I am not happy as the sales person gave me wrong information on the car's warranty and now I had to pay for a service and a petrol sensor that was still under warranty. I took the car for a service last year end of October, not with Renault as I was told I don't have any services left... I paid R2800, then to find that the petrol sensor is malfunctioning and at that time I got a quote for +-R4900 to fix the problem. As I took the car to Renault Brits in December 2023 to fix the petrol sensor,they told me that the car was still under warranty up until November 2023 and I had one service left and they could have fixed the petrol sensor with the service at that time as the car was still under warranty. Now I have to pay all that money because of a sales person that does not know what's going on. I would like you to investigate and refund me on my money as the car was still under warranty and I was told it does not have any warranty.
