NOW Mobile Transfer PIN and Account Number

Hello.

I've been trying to get my transfer PIN and account number to transfer my service from NOW Mobile to another provider. I can't use the mobile app or website to get this information because I believe my account has something wrong.

On the mobile app, if I choose "Pause, transfer, or cancel this line", it will open a window that sometimes says it is gathering my account information and then nothing happens, sometimes it just goes to a white page that does nothing.

On the website, if I go to Plans, click "See details" for the one plan, and then click on the one line available, it will show a progress bar at the top of the window then nothing happens. Using web developer tools to look at requests, I see a 500 to https://api.sc.xfinity.com/now/mobile/line/<uuid-looking thing> and https://api.sc.xfinity.com/now/notifications/line/<same uuid-looking thing> with the response {"error": {"errorCode": 500, "errorMessage": "internalerror: Exception raised by Biller-Amdocs System. See details for more."}}

This happens across multiple mobile devices (two different iPhones and an iPad), a macOS laptop and a Windows desktop, with Safari and Firefox. I don't think this is a me problem, something must be wrong with my account.

I've been trying to work with chat to get this information for a couple days and I haven't been able to get this fixed. I've been told the Advanced Mobile team would send me an email with this information but it never comes. I've had callbacks with the Xfinity Mobile team but they're unable to help since this is the prepaid plan. Also, nobody seems to be able to confirm the last 4 digits of my credit card on file. What I see in the NOW Payment Methods seems to not be accepted by agents. I see one number consistent between the mobile app and website that I am being told isn't correct.

Is there any hope?
