Hi Sam,
Thank you for clarifying.
The email address you previously used for a My Virgin Media username will still be registered with your old account, even if it's been closed. However we can merge both your old and new accounts together so that you can continue using the same email address to log in, under our move and transfer process.
I'll pop you over a PM now so I can take some more details and look into this for you.
Please find my PM over at the purple envelope.
Beth
