Unable to log into Xfinity Mobile (app or online) because system says I am not the primary user
I am unable to log into the Xfinity Mobile app on my phone or on my home computer because the Xfinity Mobile system does not recognize me as the primary user. I can log into my Xfinity account and view my services, inlcuding Xfinity Mobile. When I click Manage Mobile Account a new browser window opens with the button "Try Again." I click the button and I am asked if I am the primary account user. My only option is to try differnt login credentials. I have tried my email address, username and phone number. I end up in the same place every time--no access to my Xfinity Mobile account becuase I am not theprimary user.
I have confirmed my username and that I am the primary account holder. I've been using the same account as "primary" for over 10 years and have been an Xfinity Mobile for 2-3 years without issue until now. I have spent 3+ hours on the phone with 3-4 differnt customer service agents and the Comcast Security Assurance or "CSA" department. Still no resolution.
