If you are in the US (reasonable guess for a(n ex-)T-Mobile customer), you might want to exercise your right to pull a free credit report check and make sure it's not screwing it up.

Since it is actually a bit challenging to correctly pull your free credit report, start here: https://www.ftc.gov/faq/consumer-protection/get-my-free-cred... (Simply Googling "free credit report" and clicking willy-nilly can lead to sadness.)

In fact I'm overdue to pull mine myself; thanks for reminding me.
