Just because a manufacturer states a certain period of time for the warranty does not mean that is when the warranty cuts of. Victorian Consumer laws states:-
If a product turns out to be defective, the consumer may be entitled to a repair, replacement or refund (depending on whether the problem is major or cannot be fixed).
This applies regardless of whether the product is still under warranty.
Just because it says it on an included piece of paper with the purchased item does not mean you need to accept it.
