MG City Wheels

I bought a vehicle end October 2022 from City Wheels Gezina. I had the vehicle two days and realized that the lights front not working and that the vehicle had a miss on it , and used water but i didn't see any sign off leaks. So i took the vehicle back. They fixst the lights replace a water pipe behind the engine but the miss were still their. It was still using water. The next two day i notice that the car start smoking also. I wrote an email and took the vehicle back. I did not even drove a 1500 kil with the car in total. Im paying 6 month for a car that are standing without a motor at Exclusive Auto in Gezina, they said they waiting for specks on the motor. Im paying R9600 every month, for something that i have no use off. I had to use uber to get to work and back. Only the last two weeks they help me with a car from the floor a 1910 Toyota with over 417000 kil on the clock. I dont now what to do, i had a meeting with the manager Hanjo and sales person Pierre from City Wheels. They told me that they can only help me till month end because City Wheels are not trading any more i dont know what to do , i told them i want to give the car back and take another car with same value but they dont come back to me. Can you please assist me pls.
