Order never delivered after 2 years, but I only had FIVE DAYS to claim it

I've been waiting 1 year and 9 months for a package to be delivered with status "Your package will be delivered shortly", but it's never been delivered.

It’s a small item, ~30 EUR total cost, and it was part of a bigger order so I pretty much forgot about it.

Today, reviewing old orders, I just realized about this order. The website clearly says that the order was shipped but not delivered. I remember that back then they showed an alert on the website saying that orders were delayed because of a truck driver strike. So I kept checking for a few days without updates and then forgot about it.

It's now been been almost two years, so I wrote to the company asking for a solution.

They said it can’t be fixed or refunded because I only had FIVE DAYS to claim it starting from the ESTIMATED date of delivery, even though their website clearly shows they delivered it, and even though back then they claimed there was a truck strike to justify the delays.
