The more that AGL send reminders prior to due date - the more likely users are to ignore truly late reminders.
Even trying to give some constructive feedback has been difficult at best. All the reading has showed me that other users feel the same, and have complied with directives, yet achieve no real satisfactory outcome.
It would seem that this system is designed to frustrate users even more than receiving reminder notices BEFORE they are due.
Try to envisage how AGL customers feel about these process changes.
