Help how can I get my own phone bill account if I’m divorced? T-Mobile doesn’t want separate our phone bill?

I have no contact with that person. He don’t exist in my life. We called January the day we filed to divorce to separate our accounts & t mobile lied and they kept our account together under his name & debit card. Now it’s been months he hasn’t paid & my service will be disconnected. My bill is only $25 & his is more like $180 ish. No matter what I say t mobile doesn’t listen to me how I’m divorced & doesn’t want separate the account & even tho my name is primary on the account they treat him as the primary person & will demand his permission again but we have no contact with each other anymore. The divorce is still pending have not received anything at all in the mail too. I might need get new phone with sprint & trash this one I don't know.
