Appreciate it.
To clarify, I'm not asking or expecting Substar to start billing people who have unsubscribed, that would be silly. These are all people who, as far as I can tell, WANT to be making payments, and were at some point, and then...the system broke. And Substar didn't contact them enough to fix it, or the emails were missed, etc. This recent Feb. situation especially though seems to have involved NO emails to anyone: I certainly didn't get any on my personal account. Payment method just...vanished. So something seems to be seriously wrong on their end, and hopefully that can be addressed soon.
