Game's customer service and products defective

I bought a Defy Fridge/Freezer from Game at Fleurdsl, Bloemfontein. Since I bought it the fridge part did not work - it would not keep the products insude cold, the freezer part did work. I tried the different setting without any success & finally called to complain. I sent my proof of purchase via e-mail and had to call them back to receive any feedback. 3 days later somebidy from Defy showed up and told me the unit is deffectve & leaking gas and will be replaced. It is now Saturday and I'm still without the replacement. Game Fleurdal's customer service is horrible!
