Same here! And I tried to do it just a few minutes after I migrated my primary email (due to Verizon being so slooow with signing in & making me get a temporary password for the sub account). I need that sub account, but it keeps bouncing back to the main Verizon page & won't go to the email in order to migrate it.
Verizon is utterly useless in customer service with its stupid bot throwing out random responses to questions & having zero phone numbers listed in order to contact THE PHONE COMPANY. I wrote down the Help Desk number that USED TO be available, & another bot told me to call back because it wasn't open. I mean, jeez, I could call Kohl's CS at this hour, & get a live person! Why is Verizon so horrible in being able to contact?
