Hi, just bought an HP Instant Ink printer, I looked into it before buying and it's perfect for my needs at £1.99 per month, after the 12 month trials etc. But reading into this tonight, I read on the Which? website that HP now charge £0.99p for 15 pages whereas until late 2020 they were free.
I have a prepaid card in my box for £32 credit, which was printed in October 2019, and on the page where it outlines the cost, it says the 15 pages are Free. Do HP have to honour this?
