You can't get a refund unless you use the tube within a certain number

I was in exactly this situation and thought I'd lost the money, but at
the end of the 7 days (while I was still abroad) they emailed asking
to choose a date and station to try again with (it was an automatic
refund due to an "operational error" at Bank, and they'd chosen a
refund station for me). Which appears to be a good faith effort to not
"eat the refund".

(I've no idea if there's an actual point in time when they do give up
trying to refund and keep the money)
