Stuck with a ridiculous bill and no phone. I just want out.

Immediately before my divorce, my ex wife, without my knowledge or even a notification, upgraded her phone to a new one and locked me into a two year payment. Her kid broke my personal phone and it is unusable and too old to upgrade. My bill is now $175 a month for two lines and I cant use mine. Finally got the ex wife to get her own account and apparently her credit sucks so T Mobile is Making me pay for her phone.. Had the service for years and I have never upgraded my own phone once and they cant even get me into a replacement phone with paying $300 up front and another $46 a month on top of what Im paying now? Everyone else is giving phones away and I cant evel leave tmobile without paying off a phone I dont have. Since I have a protection order filed against the ex, I cant even contact her to ask for her to give me the phone she has since technically I own it. I can have it shut off but would still have to pay for it. I cant for the life of me believe that they cant put that phone charge on her bill, regardless of her credit. As soon as I am out of this I will never use T Mobile again and I will never recommend it to anyone I know.
