I really need to upgrade my NBN plan to NBN 12 and Unlimited Data.
I have sent an email to email@example.com but no one has responded to me, chat support has been terrible and I cannot do it online.
All my details are sent from my email firstname.lastname@example.org.
We've created an article that will guide customers in Changing NBN Plans through My Account.
In your case, the request was processed yesterday and confirmation Email was sent last night.
Feel free to search Community for help with your issue, or contact us and we'd be glad to assist you.
