Hi Nikola,
Thanks for your post and welcome to the Forums. It's great having you on board with us in the Community.
I'm sorry to hear that you no longer have access to your email address. As mentioned in the link given to you by our VIP Graham, without an active Broadband service, there is a chance that the email address is gone for good.
I'm happy to look into this further to see if there is something we can do though. In order to do that I will need to pass data protection with you. 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.
Thanks,
