Game sold me a defective KIC Fridge and Is Refusing to Take Responsibility

I purchased a defective KIC fridge from Game for my mother's care worker. It was delivered and has never worked as it doesn't get cold. A Game technician was sent out & it was confirmed that the reason the fridge won't get cold is that it was delivered without gas. He left without fixing the appliance & Game has refused to take any responsibility for the situation since then. It is now 2 weeks later, and I have lodged numerous email & telephonic complaints. The caregiver who has 4 children has been left without any fridge facilities for 4 weeks. The "customer care" consultants claim it's not a factory fault & Game is not responsible. There is no effort to replace or fix the fridge. Please can someone contact me to rectify the situation. I have paid Game R3500.00 for an appliance that has never worked. This is equivalent to theft of my money - a working appliance on delivery is required in order for the transaction to be valid.
