Was not able to port out my numbers from Xfinity Mobile

A couple of months ago, I tried porting out a couple of lines from Xfinity Mobile.  They told me that last 4 of SSN was missing or "0000" was sent.

This is not a requirement and port requests from US Mobile and Tello were rejected due to this "supposed" issue.

Opened a ticket (ECM0014315047), waited 10 days, escalated etc. and closed without any resolution.

ID verification, PIN generation etc. was not the issue for me.  They treated the issue as if there was a PIN generation problem.
