This happened with my HackSpace subscription a little back, no reminder like they used to do.
And not even my login on their website.
Things seem to have gone a bit downhill with that respect.
I eventually emailed and they told me it ran out, that was it.
You should be able to search your email for firstname.lastname@example.org and you'll get your order number, hint probably about a year ago.
But like me you probably don't know which month release you asked for.
Then email them.
But it would be nice for a reminder as you tend to get used to them turning up at the door. (To anyone reading from the press)
