Damaged Fridge

I bought a KIC Fridge in December 2013 and then I phoned Game Cresta where I bought the fridge and informed them about the malfunctioning fridge and they requested a receipt which i do not have. I then told your staff that I have bought in on credit and as it still under warranty, they must be please come fix it. Nobody is able to assist in this matter and I have meat that is currently deteriorating in the fridge. Apparently the store does not keep these invoices???? That is unheard off. How are you keeping records onfmy credit record? I spoke to Sbusiso who told me that the supplier will charge me for fixing the fridge. How is this possible as the fridge is still under warranty. I pay my account on a monthly basis without fail but I feel that Game is failing me in so many ways.
