No Help at all from you guys!!!!!

Four months ago, 25th of may 2022, i bought a vehicle BMW 1 series 118i, white in color. i bought the car at CMH Mazda Hatfield. the sales agent was lloyd. On the 27th of may 2022, i noticed that the car was smelly weirdly but thought it was just the car after driving until 08:15am the car immediately notified me about the coolant being low. so i filled the coolant with antifreeze and carried on. on the 28th after travelling from randburg with the maximum speed of 110km/h at 12:00am, the car sent an alot via the system that the coolant is low again, but now the car engine is overheating. i stopped at the garage and filled up the coolant and left again. at that very same night i informed lloyd at 12:00am that the car is overheating. on sunday i didn't drive the car at all. on the first of june 2022 i left the car at the dealership so they can sort out the issue. on the 7th of june 2022, i collected the vehicle because lloyd confirmed that there was no problem with the car. on the same day after collecting the car, the overheating smell comes back again. when i checked the coolant after a while, the coolant was low. on the 10th of june 2022, the car started overheating again and i immediately call BMW to assist me. they said i must call the dealership to sort my car out. this time when it was overheating, white smolke came out. i made surre the car coolant was full and then i took the car to the dealership with a witness also. the dealership sales agent lloyd confirms that they will take it to the bmw specialists.i called webank and created case numbers. after a while, they sent the car to the bmw dealership and confirmed that the problem is the cooling system specifically water tank, thermostat hose and tube which was confirmed with a letter. on the 15th of june i collected and test drived it and the same smell was there but lloyd confirmed that the smell will go away. but on the 16th the smell didnt go away at all but the car didnt overheat until the 20th of august, that when the cooling system problem happened over and over again. i filled up the tank with atleast 6 bottle of antifreeze and this very same day i came from randburg. After that happened i left the car with the mileage of 143300 at my yard and started using my other vehicle to go to work. so from the 25th of may, this car has been giving me problems with the cooling system. i am not happy about this because its been 4 months after taking this car and my life has been a rollercoaster. i took the car in for service on the 13th of september 2022 at the same place where the first fixed the cooling system and when i told them that they changed the cooling system, they said its only the water tank according to their past history with this car. Now i am dealing with charges that i am not supposed to deal with because the car is still overheating and the 10k is on my name even though 6month period has surpassed. According to Section 56 (2) of the Consumer Protection Act (CPA), the consumer has the right to return a vehicle to a seller within a 6-month period under certain conditions. However, the CPA only applies to suppliers who sell cars during their ordinary course of business and not to private sales between individuals. I recently took the car to BMW montana the day after i collected form bmw Specialists(RK auto services). they gave me a report stating all the problem with the car from battery shock to suspensions to armbush to cooling system leaking again to parts that are on the car that are not original manufacture parts. The bill now from BMW montana is R45000. Norman the manager refuses to change my car or cancel the deal so i can pay the shortfall. they using this strategy to not be responsible at all after 6 months.

i am not happy i am tired and i want a different car from now on. i cannot carry on like this i am devastated, i am stressed, i am so angry.
