Hi Jayne9, thanks for your post on our Community Forums and a very warm welcome to you!
Sorry to hear of desire to access what appears to be a former E-Mail account.
We would have to advise that E-Mail accounts are only issued to active subscribers and once their services are disconnection, there is a period of up to 90 days to utilise the E-Mail address that was held with their active service.
Presuming I already know the answer to this one from your post, but does cancellation of our services happen to be within 90 days?
Thanks,
David_Bn
