What is the problem with the deactivate link? Every time to try to do it is says "deactivate link failed try later". I think we are being forced to use both services together.
If you go into My Account under Profile ,there is a prompt that says you can deactivate the link between vz central and managing your account with the same sign in. Like I said when you click on deactivate link you get the error message, deactivate link failed try later,. We are being forced to use both at once.
