they sold us faulty vehicle

We bought a toyota yaris with a cash amount of 70,000. And it was on the 28th of March 2015 a car was delivered on the 29th of March and on the 1st of april we were driving the car from rustenburg to eastern cape it just broke down in Klerksdorp and that was shocking us because we were promised that the car is 100 percent. We called them and when we asked them what must we do to this situation they were dropping our calls and we slept next to the road, we sent some messages to this Ishmail he never responded to us, we called scorpion for legal advive they promise to help but it seems they failed us too, we ended up towing the car back to rustenburg and now we don't have money, the car is dead here and it just died with 2days of purchase we tried to get help from Awaiz since the day of incident they are running away, we want them to take their car and give us our money back because they got the money but we don't have a car its dead, I am mrs.
