them. We have an account with debit cards that we never use. Because
of that, the bank did not issue replacement cards - a fact I found out
two days before the expiration date, and two days before leaving on a
long vacation where I expected to have use of the cards (for foreign

so one was still valid. I'm pretty sure that had we waited long enough,
they both would have expired without replacement.
So while debit card services were not cancelled, technically the card
itself was cancelled for lack of use.
