Pathetic Service from Hell!Be careful where you spend your money!

I bought a car three weeks ago, and was told it was bumped only at the back no other problems, and that the car was never in an accident , and it has a service history. I gave them a week to fix the problems in that car, they fixed the back part. . When I went to collect the car, it had no petrol so I poured R200 petrol on my way home, and while driving , I realized the petrol was smelling , I got home and within 5 minutes of packing the car I realized that the petrol tank was heavily leaking, and the car had a whole underneath and you could see the car was in an accident as the petrol tank was patched and bended. I called Mark and notified him immediately and he said I must bring the car on Monday as they are closed , they don't work on weekends. Was stacked with a dangerous car that leaks petrol, and I had to make a plan and find the mechanic who will close the petrol tank as petrol was all over the yard,I took images and sent him. I took the back the car, and Mark said he was not aware that It was leaking, and that it had a problem, and I realized that , that is why the car was empty cause if it had petrol I would see it leaking.. I asked him to refund me the money I spent for fixing the car and it took them two weeks to refund after I called them , sent them messages and screamed for my money.. Now the petrol tank is still leaking and the sales man Mark said I must not ever call them back again because I'm rude, I complain a lot, I felt that it is within my right to complain as the car I bought was R85 000, I'm still spending to fix the stupid car cause Mark **** to me and does not want to help me.. Do not buy a car at Auto Fame it's a total waste of money. The service is pathetic , and ridiculous..I even argued with Mark for a spare wheel and the tools that comes with the car as i was given stories, now go at your risk!.
