car broke 2nd time after two months of not having the car

Good day please May I be assisting with consumer act contact details, planet 42 mistreating customers I regret everything, when I took the car I strictly explained to the sales consultant that I need it for work. I collected the car on the 20 November first premium was due in December the car broke in December then taken to a workshop. I didn’t have the car for the entire December until the end of January. Now second week in February car doesn’t get to gear 3. Which had to again be taken to workshop. The car hasn’t been operational since collection it’s been on fault since day one. I'm supposed to pay installments for the car that has not been working for full two months when I spoke to the consultant was told they cannot change the car I must sell it myself to a dealership then only then I can get a another car. 1, the car is full of faults which dealership will accept such a car, So, I must pay for a car I cannot drive. I understand I’m liable to pay however how do I pay for car that is non-operational I’ve never had any joy since I collected this car. Now as we speak this car is broken again. It was taken to workshop,

1 , gear number 3 doesn’t work it only goes to 1 and 2. abs and engine signs are showing. 3, there no power on gear 3.

How am i supposed to work and generate an income with a dead car I never even got an opportunity to enjoy this car. I need a car to wok and generate an income.
