Don't expect a refund for damaged goods

On 4 November 2015 I bought a PC computer game from them. After loading and registering online at home I started playing, only to have the screen freeze after about 10 minutes. Had to reboot. Went online and saw hundreds of complaints about PC version of this game freezing. Went back to store on 6 November and asked for my money back. Very, very young manager refused, said it is my fault the game doesn't work. I have spent thousands buying games in that shop and now they have this attitude. According to SA consumer legislation they MUST repay a customer if something doesn't work.
