The internet as a whole.. actually proves that these sorts of things DO work, to some extent.
For your problem, no. There is SOMETHING wrong on the back end, where your email is not in the right system, etc, for it to send out the bills.
But otherwise?
As you can find 1000's of forums out on the internet.. there are people out there, who have found solutions to USER fixable, work arounds, tweeks, upgrades, etc to things... that the hardware/software manufacturer still doesnt have on their 'solutions'.
As an IT person myself, 8/10 times, when i need to fix something i am not sure of... i find the information on how to fix it, from a google search and someone else who has figured it out.. not going to the manufacturer.
If you look through the forum, there are MANY users who have found solutions from here.
Unfortunately, yours is not one that can be solved this way likely.
If its something that has to be fixed rogers end, the only means you have, it to keep calling in.. pressuring them to escalate it.
have them look at ANY parts of their system with your profile that has your email address in it.
have them try and remove, and re add it.
etc.
