Pathetic service and endless issues with purchased vehicle

Very unhappy with the service from InspectaCar Pietermaritzburg. Purchased my vehicle in July 2020. A new battery was purchased in May 2020. In August the battery was dead. I got a replacement battery and the car went in thereafter for them to see what was drawing current from the battery. I used the car daily ever since. A few days ago I didn't use the car in the morning, tried going out and the battery was dead again. There is nothing wrong with the battery, the fault was not sorted out in the first place. I now have to be inconvenienced and send the car back in. How am I being compensated for not having a vehicle to go to work? There has been endless issues and I wish I could just give the car back. Pathetic service.
