Thanks for your post and welcome to the forums. Its great having you on board with us in the Community.
As mentioned by Graham above, there are a few exclusions as to whether or not we can delete the email address. To check if this is something we can arrange, I will need some information from you and may also need to pass data protection.
I have sent you a private message regarding this and will investigate further once I receive your reply. Just click on the little plum envelope at the top right hand side of the page to access your inbox.
