Please let me know if you can see any such information on the printer box, any attached card, or any other source, to better understand it, as much as I can see I could not locate any Cashback offer for the specific product from searching online.
Be aware that I'm just sharing my personal experience with HP products and promotions and experience with the HP site, I'm not replying on behalf of HP in here but just trying to understand what might be the reason for this misunderstanding.
I'm aware of Cashback offers for select HP Officejet, Laserjet printers in the UK, not for lower-end HP Deskjet printers.
