Unfairly treatment from Weelee Centurion

I bought a Hyundai Getz on Monday the 4th of may 2026 at Weelee Centurion I have viewed the deka report and agreed upon the purchase of the vehicle as the dekra report indicated no fault to the enigin of any sort. On Wednesday the 6th of may the vehicle already did not want to start. Frustrated as a single mother I called Weelee Centurion and told them this vehicle is not able to start and I am not comfortable with the purchase seeing it is not reliable already on the third day. I was already told I will not be refunded but they will run a diagnostic to assist me to resolve the issue . Very unhappy with this comment I managed to get the car started and drove it to Weelee . They took the vehicle, ran the diagnostic and told me it is the battery and they have replaced it I drove off thinking now the vehicle is tustworthy but also stated to the manger if there are to be any other issues I will have to insist to be refunded. On Saturday the 9th of May while driving home I noticed it is as if the vehicle is losing power thankfully close to home. I noticed a disel smell driving to my parking space. Before switching off the vehicle I noticed the fuel indicator was dropping drastically. Very concerned, I got out of the vehicle just seeing the disel all over the place. Realizing my life was in serious danger. I called Weelee again very distressed. I was told there is no one to assist me at the moment. And the matter has escalated. Sunday I called again, making them aware I am a working mother and now I will have to leave work to go to their premises again. I was told the manager will call me before 09:00 on Monday the 11th of May. Not receiving the call . I arranged to go from my office traveling to Weelee at my cost again. And was told the diagnostic have to be done again. I do not feel this is fair treatment and I have already lost a the money filling up the vehicle with disel just see it be wasted on the ground. Taking car insurance and I am not even able to drive the car. Not even to mention this is supposed to be my transport and have to Uber myself and my daughter to the destinations we need to be.
