Email Bill notification not working

For reasons unknown, I stopped getting email notifications of when the Bill is ready to be viewed and paid.  This is for our business account on both Business Internet line to the office, and our Mobility phones.  When I phone Telus, of course it's MY problem.  Having never changed our email address on file or anything else since 2006, this is very frustrating.  It's frustrating because it happened last year in Aug 2024 for the first time.  I  phoned Telus last Nov and (you guessed it) it's "fixed", but it's not because again we are not getting email notifications of when bills are ready.  This is obviously not a big deal to most people, because any logical person would think that "you know you have to pay a bill, why not be more organized?"

The problem is for a business faced with paying a lot of bills, and having been forced to go paperless by the Telus overlords, we don't have time to go looking when a bill is due.  We need a notification.  Telus doesn't seem to think they have a problem, with both Mobility and Business Internet all of the sudden not emailing the Bill Notification to the valid and working email address on file.

Does Telus have the internal strength to fix something like this?  Or is it intentional so we keep paying overdue and late fees?  Personally, I think it's the latter.  I'm sure some accountant somewhere in the chain thought "wait a minute, we've got 2 million customers, if we get 1% of them to pay a couple a bucks a month in late fees, that's an extra few million revenue in a month"!  And I think I'm right, based on who I've talked to.
