It's a misconception that we only have a 1 year guarantee. This is Apples take on it, but it is hidden away. I am not saying that it is easy to get things done, but if you are armed with the correct legislation when you contact the seller then you stand a better chance, but you may need to follow up with a county court case, if they play hardball.
