Hi there @raghda
Welcome back to our Community, sorry to understand that you're still having issues with your email address. As our VIP @Graham_A has advised, it sounds like your email address may have been orphaned if it was not linked to an active broadband account.
I have not been able to locate your account from here I'm afraid so haven't been able to check, I'll need to pop you a Private Message so we can take some information and go through security. Please do be advised, if the email was not linked to an active broadband account, it may not be possible to get it back.
Look out for the purple envelope in the top right of the page and pop me a reply when you can.
Cheers
