Going against his words

I bought a car from mcdulings Leon was helping with the process of buying the car they delivered the car and I pain them R800 which was initially R1200 for delivery. When I saw the car I checked the car the condition of the tyres was not good I spoke to the guy he said it's fine I must buy the new ones and send him the invoice with the licensing invoice I was only refunded for licensing when I phoned him he said he <br> only received the licensing. I started afresh send him the documents I phoned him did you get them he said he will check then weeks gone by THE IS NO FEEDBACK I phoned him again he speak to his manager till today. He polished the car nicely so that I can't see any dents but after washing the left mirror and the bumper has dents if I tell him he say I must buy the Polish he will pay while he knows he is lying I was busy fixing the alarm that was faulty if I tell him he tells me stories. I bought this car in June 2015 Polo sedan 2014 model this guy's are pushing targets not giving customer service I didn't lock my car for 3 weeks looking for help they have a terrible service
