Motor Industry Ombudsman of South Africa- We Buy Cars is reaping us off

I called the sales lady Samantha Clough who was helping me with paperwork, and she said I must bring car back the next day. I did and they took to Maestro at Centurion to fix it. Now the leaking problem is back and this car is only less than 2 years, and I'm still paying for it. I contacted Samantha Clough, who ignored my whatsapp and calls, then Isabella Siwela or Sibanda who also works there advice to call their customer service, which I did and they me the car is now my problem.
