Hi KarrieG55, thanks for being part of the Neighbourhood.
We are sorry about the delays with AGL Messenger currently. I would recommend downloading the APP and messaging us through there, that way you'll get a notification when we respond instead of having to wait for a response.
You can find some information about estimated bills on our website here. Just bear in mind you'll also have estimated reads on monthly billing with a basic meter. If you're not able to find the information your need on that page, please get in touch with us directly here,
Kind Regards,
Jenna
