Based on your posts in this thread you have not actually created a new email address but you have tried to change the username for an existing address to a new one that does not exist.

If you can to create a new virginmedia email address you do so via your My Virgin Media account > My Profile > Manage Accounts.
In that section you should also see the option to cancel the usename change that you have attempted. If you cannot remember the password for the existing email address to access the My Virgin Media account then use the Forgotten password link with the existing address.
Checking the email address you posted above in Mailtester.com shows that it does not exist.
