Webuycars not assisting in fixing car battery and refunding me my R5000.

I bought a car at webuycars Mbombela branch 2 weeks ago. The car battery died a week later. The vehicle has an electrical handbrake therefore i am unable to push the car. The vehicle died in my driveway. I was unable to go anywhere during Christmas, I was blocked in. This has completely ruined my Christmas. I am a mother of a 4 month old baby, I am still unable to go buy any necessities for my infant. The sales person who sold me the vehicle Mbulelo is not answering my calls anymore. I called using the call centre and he still refuses to answer the calls. To make matters worse they have not refunded me my R5000 deposit. This matter has been outstanding since i collected my vehicle on 13 December 2025. The F&I assisting me Jason has been giving me the run around concerning my refund. I do not have a working vehicle and i do not have my R5000. As a mother how am i supposed to explain to my children why we spending Christmas indoors and not even able to enjoy ourselves due to the negligence and lack of urgency from webuycars Mbombela branch. Honestly, they have ruined my festive in the worst possible way and their employees who were assisting me in that branch seem not to care at all about customers. I am now stuck with a car that is not working in my garage while they are enjoying their festive to the fullest. Worst service ever from Webuycars
