Worst service

I have had the worst service with these people. I purchased a car from them (via bank finance) on the 18th May the next day the car had a loud sound coming from of the Engine when i opened the bonnet I discovered that the air filter was broken, i informed the Kilokor workshop(Jeremy)and they said it was a minor issue which i could get fixed at a local RMI in my town(Rustenburg). I took the car to a local RMI and the mechanic there said he needed to strip the engine because the noise was caused by a broken timing chain . I contacted Kilokor regarding this and they said there was no need to strip the engine and so I needed to bring to take the car back to them in Joburg . On the 27th of May I drove to Kilokor when I got there i met Jakkie who told me to take the car back to a local RMI and that Jeremy was wrong to suggest that I bring the car back to them and also confirmed indeed the engine will need to be stripped and it could take few days to get the job done . On the 28th of May the car couldn't start. I had to tow it to an RMIbon the 29th of May and the mechanic again refused to check it saying I needed to take the car back to the dealer . I informed Kilokor workshop and they arranged a tow truck for the next day which was a Tuesday. The car was apparently fixed and ready for collection but I informed the dealer on the 2nd of June that I didn't want that car anymore because they gave a defective car. The dealer refused to cancel and says I need to come collect the car
