Bad dealership

Thys is working under this name in Boksburg About a month ago we traded two of our car in at this dealership for an Tiggo we found problems on the car and Tommy gave our cars back then Thys took them from us. Before we took control of the car we are driving now he said the care is in very good condition, there is no problems, my hubby took the car for a drive with thys my hubby told him he smells oil and his words where that just serviced the Car. Great we took his word for it, we got home parked the car the next morning my hubby pulled the car out found oil leaks so we went back, and also a problem with battery thys said he is not going to give us a new battery, so my hubby came home with the car after he told thys if he gets stuck thys will come and help him the next morning my hubby went fishing got stuck in a ver dangours part of Kemptonpark phoned thys he only got to my hubby at 8am. Took him a battery so my hubby come back home parked the car, The next day battery so flat could not start so my hubby had the other battery on charge and told him that the battery is flat. He then kept the car fixes the alternator then that problem sorted. Still oil leak and it smells dreetfull, we went on a 71km trip from home and there the car got stuck where my wife had to walk 7km to me with leg and hip problems, my wife emailed him and wts app him and he said he is busy he will not come to our aid, that was twe weeks after we Baugh the car, battery dead does not charge and we had to call our weekend short because of car problems, we got back the Saturday the Monday the 21st the car did not start and my wife and daughter both had to push start the car, took the car toe him and said he will look at what the problem is after I had a fight with him. The starter was broken, still the oil leaks are there, then we told him and he said he is not replacing the battery so we did, went we went to register the car on our name we could not get the car through the test because we know it will not go through then we found a person sympathetic to our cause and let it go through. Know we have a problem still oil leak the car is smoking like it’s on fire, after all of this thys still refuses to fix the problems on the car, I have been doing my research that our consumer rights On second hand cars is that we have a six months satisfactory and we are not happy, then we send him a message asking him to trade the car in and give him10k for other car he then told us he had COVID how can we believe him

From the beginning his word to us is the car is in good condition no problems, we are not even driving the car a month, I hope we can get a solution to this problem.
