Still getting a bill from the old provider

[PatC]

I have been with AGL for nearly 3 months and I have just received an invoice from my old provider for the same period that I am covered with AGL. 

When we change providers, does the account at the old provider not get cancelled automatically without me having to ask them to?

Hi PatC, that is right, the previous account should automatically close. It seems like something has gone wrong here, so we can review and assist, please get in touch with the team via messenger in My Account.
