iPhone Puk code

I have a free government issued phone and when I try to get the PUK code from T-Mobile they said that they’re not allowed to look at it because it’s government issued. I can’t set up a T-Mobile account because my phone is disabled and they wanna verify my phone number. If I try to open with a different phone number they tell me it’s not right, so what am I supposed to do
