Certainly is a way, but you may not like it. Betting is that the virgin.net address is one of those that should have been closed down when the old dial up service it was linked to closed or was one which should have only existed for 12 months after VM sold its ADSL customers to TalkTalk. In that case or in the case where it was linked to a VM broadband account but isn't now VM will simply close it down, if you ask them to.
In the long run it will be closed anyway as VM clean up their systems.
It you want it closed now wait here till a VM team member contacts through this thread and they'll get organised for you.
