Did you return it after their deadline? Do you have proof of posting? What was the problem with the item? Did you tell them? Perhaps a carefully worded letter might help. I suggest you contact Trading Standards for advice and help. Statutory rights are not affected by return dates. So, if it's not fit for purpose they cannot say you didn't return it in time. The return date is if you've changed your mind. It's a cooling off period and you can return in that timeframe if you change your mind. Here's a couple of links. https://www.amazon.co.uk/forum/deals?_encoding=UTF8&cdForum=Fx1DEIHNWYF5SA9&cdThread=Tx3B6AA5Q8RHYE2 This one is more important; https://www.amazon.co.uk/gp/help/customer/display.html/ref=hp_gw_repol?nodeId=1161002 and it actually explains the confusion - they call Statutory Rights the same as Statutory Cancellation rights. Statutory Rights are a consumer protection law if goods are not fit for purpose. the 'Stat Cancellation Rights" are different - just about changing your mind. It could be they have used them interchangeably in your case. The second link has the important bit at the very bottom.

For more information about these statutory rights, please visit Adviceguide, a Citizens Advice website at: http://www.adviceguide.org.uk/.
