Terrible service, bad attitudes, vehicle issues not being seen to

I bought a car from Hyundai Plumstead 2 months ago. When I bought the car, the sales guy said the car will be ready for me 4pm the next day. Upon taking receipt of the vehicle, there were so many issues wrong with the vehicle - the reverse sensors were not working, the windscreen was chipped, the rear lights were all mixed up amongst other issues. The car was taken back to them for issues to be sorted out. The workshop where they had the vehicle phoned me to say that I must pay around R300 per chip to repair the windscreen, which I said I was not going to pay so Hyundai said they will replace the windscreen. Upon getting the vehicle back, there were still issues on the vehicle and it had to be returned again and I had to wait weeks for the licensing to be done. Up until today, the aircon is not working properly (switching on and off, and causing lag on the engine), the roof is rusted, there is a rattle on the rear seat which was previously loose, the button to lock and unlock the doors keeps getting stuck, there is a fluid running out under the car and spraying out of the front grill, there is a noise on the suspension, a noise on the driver side by the seatbelt section and the car is chowing petrol! Ive driven from Brackenfell to Plumstead (37km) on a few occasions already on my account with no success. Hyundai refuses to give me a courtesy vehicle or compensate me for travelling costs while I sit with 2 small children (7 and 5) who go to 2 different schools. The sales guy has gotten a really bad attitude with me, they are not responding to my emails, messages or phone calls, but I still need to sit with all of the issues not being resolved. This service is terrible and myself and family am suffering with no assistance or sympathy from Hyundai Plumstead.
