After wasting about an hour and a half trying to figure out how to fix it myself, I wasted another hour trying to find support options until finally deciding to make a post here. For the record, the t-mobile app currently tells me "We're working on improving your app experience" and doesn't do anything, and several links to "chat" just take me to a generic support page.
Basically, I got a message this morning saying my account was suspended because I didn't pay. I had autopay set up, so I was obviously confused by this. I logged in to check and now there is a flag saying that I need to update my payment method. I've re-entered the same exact info multiple times, and either it's not updating, or my card is not working, because I keep getting the message. Even weirder, when I try to just cancel autopay, it will say I've done it on some parts of the site and then say that it's still on in other parts.
Whoever reads this, if you could please either help me with figuring this problem out, or let me know of a way I can get other support options working, I'd be extremely grateful. I've done autopay with the same exact card for tons of things in the past, so this has been pretty frustrating.

Call Customer Care. They can get your payment.info entered manually and make sure everything is setup properly.
