Final bill with negative total due amount

I’m in the same situation, except that T-Mobile apparently has a logic hole in their way for me to clear this up online.

So, the letter says "This is your revised final bill. Please pay online via t-mobile dot com slash guestpay.". The "Total Due" is like -$5. I go to guestpay, it makes me type in my phone number twice (it hasn't changed), then says "We are unable to accept guest payments from the phone number provided at this time. To make a payment, please log in" with a hyperlink to the "my" t-mobile login page. It doesn't let me sign in with my phone number, I can only submit by email.

It then says it needs to send a code to my email for verification. I type in the code, then it says "Link your phone number to your T-Mobile account. Enter the phone number below to link your account, and we'll send a confirmation code for verification." I enter it and click Next, get a little spinner which then goes away, and that's it. Nothing happens. I try again, same result.

I open up browser Dev Tools > Console tab, and there's a JavaScript error for each Next click that says "Failed to load resource: the server responded with a status of 400 ()". The Network tab request to checkMsisdnV2 (with redirect instruction to signin) has a response of "code: non_tmo_msisdn, description: Make sure your 10 digit T-Mobile phone number is correct." :laughing:

This is ridiculous. The form auto-formats the phone number I type in. It’s the same number I used on the previous form, and every form T-Mobile’s asked for, even when I had the account active.

So, for some reason, T-Mobile is making me "link" my phone number to the de-activated account, just to look at "guestpay", but they won't let me because the phone number is not already a T-Mobile phone number :rofl: this is asinine. This is a billion-dollar company? Maybe let me manage it for a while...

So, again, I’ll need to visit a store, explain this ridiculous complicated scenario, have the rep give me a strange look and say “but it should work online”... hopefully I won’t have to show them why it doesn’t work while they’re surrounded in a busy room, just to make sure that there’s not more snafus with this bizarre contradictory letter. How am I supposed to pay "-$5" anyway? Should I send them a check for -$5 that when they cash it transfers money from their account to mine? ¿Qué?

I’ve seen bizarre snafu trains like this that cost people money, from technicalities like this, logic holes, because the company's system got overwhelming to the managers of the system. Now I feel like I tener to clean this up because a technicality ese they should already handle (or at least let me handle it online easily) could cost me money.

Anyway, that's my Ted Talk. Maybe someone knows a workable online solution, otherwise I may leave an update to how it goes with a store visit. So lame that this digital tech company requires an in-store visit to take care of something so simple.
