Get a notification "before few hours" when a service will be paused due to unpaid invoice
LSN already sends notifications for unpaid invoices. And, the latest one sent is "before 3 days where the service will be paused".
I suggest getting another notification before 3 o 6 hours to the pause of the service with a subject that starts with "Urgent".
I think that it is a common user behavior to think "I still have time" when we still have 3 days (and forget it later) :).
