Sale of goods act, please help

I purchased an AEG Santo fridge freezer from a discount appliance website which was brand new, this was about 2 yrs ago, this fridge freezer has now stopped working, am I right in thinking that the company I bought it from should attempt to repair, replace or refund as per the "Sale of goods act 1979" I can't find the original receipt but do have a credit card statement with the transaction on it, any help or advice would be greatly recieved before I call the shop

hi and thanks for your reply, i didnt take out extended warranty, i rang AEG and it was them who told me about sale of goods act and they say there fridge freezers should last between 7 and 10 years we have only had it just short of two years!!
