Issues with identity verification, again.

In 2023 I added 2 mobile lines to my Xfinity account for myself and my wife. The verification process was horrendous. As soon as they attempt verification the "3 questions" don't pop up and the order is immediately cancelled. Told me to contact the credit bureau, which also led nowhere as they said nothing was amiss. Somehow customer service was able to push it through and we got our phones within a few days. 

Today in 2025, I am attempting to add another phone line for my daughter. Again, have to "verify my identity", as if 2 phone lines currently wasn't enough. Once again, the 3 questions don't pop up, and the order is immediately cancelled. It's beyond frustrating at this point trying to jump through an impossible hoop. I need actual help because the supervisor told me to wait for an email that never came. The supervisor on the phone never picked up after being on hold for 35 minutes.

Thank you.
