Hi simon_nsw!
Welcome to AGL Community!
There can be a few reasons why your gas account is still showing as in progress, given that you've organised your transfer 4-6 weeks ago, we still may be waiting for your transfer reading to be completed. Once your transfer reading has been completed, your account will then be established and you'll receive a confirmation notice from AGL.
You can get in touch with us directly on your AGL My Account here and sending us a message, we'll then be able to check that for you.
Kind regards,
-Nam-
