Strijdom park Toyota terrible customer care ethics

On the 29 August 2019 I purchased a 2014 BMW 116 from imperial Toyota Strijdom park. I was told in that a full service and road legal check was conducted on the vehicle but in less than 3 weeks from purchase the vehicle started experiencing overheating issues. The sales person Dhaveshan then told us to bring the car in as it was still under warranty. After 4 weeks of empty promises from Dhaveshan about the progress on fixing the car he then transferred us to his supervisor Ricardo who informed us that absolutely no work had been done over the four weeks and furthermore we would have to pay for all repairs on the vehicle and they would not take any responsibility for selling us a vehicle with overheating problems. Despite our disagreement we decided to pay the expensive quotations in the hope that the problem would be completely fixed. After an additional 2 weeks we were told to come retrieve the repaired vehicle but it didn't even last 2 weeks in my possession before the problem began to arise again. We checked in the vehicle again to the garage on their advi*****t and after another 2 week wait we were then told that the garage would assume absolutely zero responsibility for the issues faced with the car and the reasons given were due to negligence and that they had found what they suspected to be marijuana seeds in the vehicle. Despite all my efforts to prove that I was not negligent I was then told to collect the vehicle at the workshop were it was being fixed. On arrival at the workshop the mechanic made me aware that the garadge had refused the replacement of essential parts(thermostat, water pump and others) in the initial repair of the vehicle. The mechanic was attempting to clear his name and said that he told Ricardo that the repair wasn't guaranteed but Ricardo attempted to decrease the price of the repair by removing these parts. I currently have a non running vehicle and the garage refuses to help despite the fact that I had the vehicle for less than a month and it is still under warranty. They have turned what was supposed to be a sweet memory into a bitter terrible ordeal and I wish I had never decided to deal with Dhaveshan or Ricardo in that garage. I have recieved significantly better service from less reputable garages and am pleading with anyone who can help me to contact me as the vehicle is still under warranty. I strongly suggest that potential buyers steer clear away from this garadge.
