Port transfer pin

I am now on my 3rd call to try to get a port transfer pin for my Xfinity mobile number and keep being told there is an issue with my account. Both the app and Xfinity mobile webpage only show my video/internet/home phone account and not Xfinity mobile so I can not generate the pin through those options. First call I was on hold for just under an hour and never reached an agent and had to end the call. The second call I was on hold for around a 1/2 hour then an agent tried working on the issue and said he had yo move it to a higher support and would call me back in 1 hour. That call came 2 1/2 hours later when I wax unavailable so hence the 3rd call once I finally reached an agent it was the same routine with no resolve and waiting for another call back. The reason I am switching carriers is because I was charged $398 dollars and was told I used 22 gigs above my limit yet I have not changed his I use my phone. The reps have said they didn’t even see me with Xfinity mobile which I have had since its launch. (Former employee) I wax also told they couldn’t do anything about the charges because it’s under an employee account and I would need to speak with HR and the last time I tried that I was told you are no longer an employee we can’t assist you. Thanks for 26 years of dedicated service!!!!
