If you are not the account holder, ask that person to sign in and delete the email. If it is a primary account, or your broadband account is not active, wait here for a member of the Forum Team to arrive and they can confirm things and delete the account. This can take up to a week, so be patient.
Did you manage to follow MissPasko's advice and remove the email account yourself? Or do you still require intervention? If the latter then please post an update and we'll message you for the pertinent details.
