Request for Assistance Regarding Vehicle I bought from Webuycars

I am writing to you with a heavy heart regarding the car I purchased from Webuycars dealership in Cape Town. Unfortunately, I am experiencing ongoing breakdowns with the vehicle, which I previously reported to them after 3 days of taking ownership. Since the purchase, I have spent approximately R80,000 on repairs, and I am still making payments through Standard Bank. This situation has taken a toll on my mental health, as I have been struggling with depression since purchasing the car. Additionally, my children are currently unable to attend school due to transportation issues, as there are no public transport options available in our area.
