Can't port in xfinity mobile

[weng1235]

I want to add one line by BYOD. But when I order the sim card online and choose keep my own number, it says "Sorry, looks like we are having technical difficulties." But if I put my other google voice number, it can go through.
I also went to the xfinity store, but they can't resolve my problem after spending 4 hours and mutiple calls to the back-end by the agent.

I think it's because this number was with Xfinity before. When I ported it out 6 months ago, Xfinity mobile didn't clear their system completely. On Xfinity's record, my number is still with Xfinity.  So it doesn't accept that number to be ported in now.
