I've had an old ntlworld email account for years and I'm, no longer able to access the account. I am not a bill payer so don't have it linked to an account to reset my password and therefore require the email address to be deleted.
Thanks for your post and welcome to our community.
Sorry that you're having some issues with the email service, we can certainly have a closer look.
I'll pop you a personal message and we'll take it from there.
