Quality cheapies

In June 2018 I bough a car from Quslity Cheapies , corsa 1.4 model 2005. I experienced major issues on the car within 2 days , engen was leackig water and all the lights were not working. I then decided to return the car and ask a refund . They refused to refund me , they gave me 2 options , option1 to wait for the car whiile they are busy fixing it and option 2 to take another car which is worth the same price as the faulty one . I had no choice but to choose option 2 which also gave me a lot of problems such as , crank sensor ( they fixed this at their own cost ) , i then experienced another problem where the car doest start , i took this car to them they refered me to their machanic who would fix the car but aftet few days the car would do the same thing , i logged a complaint on Ombudsmen but unfortunately the outcomes was on their favour .

Unfortunately, i had to leave JHB and relocate to Eastern Cape beacause of work. Am now sitting with the bellow problems:

1. Am stillsitting with this car which doesn't start sometimes or just stop in the middle of the road. 2. I still owe them R4000 as this car wasn't the exact value as the 1st car . 3. Sitting with a car that wasn't my choice .
