Unlocked s21 Ultra showing as "Unknown Device" and not supporting 5G or Extended Range LTE on My Mobile account

I'm dealing with this as I'm typing this!  I bought 2 phones a few months ago direct from Samsung,  I'm switching to Verizon and Tmobile is playing dumb, or are dumb and taking forever to unlock them. They blame Samsung, then blamed Verizon. I got Samsung on a 3 way call and they Samsung guy had to EXPLAIN to Tmobile how to rectify the situation. Round and round we go!
Like the others my IMEI numbers do not show up on the Tmobile site, yet there my phone is! So you can't check the status of the unlock unless you call. Then you call and chances are you're gonna get a person reading off the screen who has no idea what they're talking about.
Such BAD customer service, I can’t wait to be done with Tmobile!

Oh wait, he just told me to try clicking the “unlock” button lol
