selling cars that arent serviced

I have purchased a vehicle from IC Auto Roodepoort which is financed by ABSA. I am not happy with the car. I trusted the dealership when they told me that the car was serviced in May 2022. The light bulb of the car on the right side stopped working after only a few hours of driving the car. I was then asked to bring the car into the dealership so that they can insert a new light bulb , after two weeks of driving the car it started showing a notification that it needs service . I then sent the picture of that notification to the salesman , and I was asked to bring the car in to get checked by BMW . When I got to the location the car was checked by a random mechanic which I was not happy about , he removed the service sign and confirmed that the car was last serviced in 2021.

With all of this being said I was told by the manager of the Dealership that they will get me an invoice to confirm that it was serviced , if they can't then they will contact me to come collect the car and get it serviced by ''uncle BOB" . This morning I suggested that they cover the invoice for the service and that I take them to BMW, but they refused .

I honestly cannot be liable to pay for a service for a car i only drove for two months, please advise what the procedure to return the car and how long it takes.
