Funny A5 2019-2020 Diary Calendar: Well organised book with day/week pages and priority/to do columns on every page

I purchased this to find it was for Dec 2018 - Dec 2019...not for next year as advertised yet the slogan on the back says - 'there's always 2021'?! The only option I have been given is to return (despite it being a completely useless product) which I'm not going to the hassle of doing to purchase packagibg etc to send back. Straight to the bin and money lost.
