One time I had a defective Ipad. It was 3 months in the warranty period of 1 year. I brought back to be met with obfuscation that I had to contact Apple to deal with it. I protested vehemently and told them that it was their responsibility to honour the warranty. They tried to fob me off. I started raising my voice in the shop and was told to wait to speak to the manager. She came out and told me that I was correct. They will get replacement. When it arrived after driving 60km to get it, I was told that the warranty would be only 3 months as it is refurbished.
I was appalled and mentioned that "if you went to buy a fridge after yours was not working would you accept a second hand item"? I was fuming and threaten to go to consumer affairs. This was quickly met with a written warranty for another year. But I insisted on my money back or a new one. After a while they decided to give me a new one.
You have to stick to your position and stand for your rights under Australian laws...I refused to be fobbed off and it paid off.
