CMH WHOLESALE IN BOKSBURG

Hi there, my name is nikita. I need help or advice urgently. I purchased a vehicle from cmh wholesale in boksburg on Saturday the 15/02/2020. The vehicle broke down on my way back home from jhb to pmb on sunday the 16/02/2020 at 2:45pm.. We got stuck 10km away from harrismith. When i contacted the dealer they said they cant do anything as they are a wholesaler and what you see is what you get. The vehicle is sold as is..please can you help me and advise if i have any rights or have i just lost my money that was paid for the vehicle? I was stuck on the side of the road with my 10year old daughter and CMH did not care. They told me straight out they cant do nothing about it. I told them i would take it further and to the ombud and he told me i must go ahead. we had to get towed from where we were stuck to the nearest halfway garage where we waited for a flat bed to tow us to Pmb. i have incurred so many costs to get this vehicle and i am still without a vehicle because the one i purchased cannot be used. I am a single mum and worked very hard to buy this cars cash, i am in such a situation right now as i cant afford to get this vehicle repaired either.. the dealership clearly was aware of all these faults on the vehicle. no mechanical faults were disclosed to me. I feel this is so unjust and *********. Please can you help me and tell me if i still have 7days to return the vehicle or what are my rights?

i need urgent assistance please :-(
