Welcome to the community!
It is quite strange that you're getting different messages for the different accounts. So that we can jump into your account and have a look around, we'll need you to contact our web chat team (aglener.gy/ChatCom) who'll be happy to help where they can!
I receive SMS mesages to alert me of upcoming accounts that will be due. Providing the ammount for that ccounts is a great help for the Electricity, do the same for Gas.
I will not be contacting anyone else on this matter, surely my comments (if they merit any consideration) can be processed within AGL.
I am satisfied my comments have been noted, the rest is up to AGL.
