I have disabilities and I want to be an authorized user on a t mobile account and they won't let me and I got mad, how is this immature?

So my parents decide to let my sister's husband take control of our t mobile account and they made him and my sister the account holder. This made me an unauthorized user so t mobile people won't talk to me now. Now I can't upgrade my phone or make changes to the plan without asking him first. I'm angry as I had full access to the account back when my parents was the account holder. They wanted him to be the account holder just so that we can have a military discount. I don't like this as I want to have control of the account. Andy told me that I'm immature because I told him that I want access so that I can do anything to it and get an upgrade on an phone anytime I want. He said to me you don't need to upgrade your phone every year as no one else does that. Well I have an iphone and iphones starts screwing up after a year. I just don't get what is wrong with me making an authorized user so that I can have access to it and make changes or upgrade a phone whenever I want to. I threatened them that if they won't let me be an authorized user then I'm going on my own plan. Andy says that won't happen as your parents won't pay a plan just for yourself if you want that go get a job and pay for it. How come I'm immature for asking to be an authorize user? What is so wrong about upgrading a phone?

So you are out of luck

I know people that have iPhones 3-4 years old and they work fine. 2 years is more common to upgrade… When you personally have the money to buy a new phone.

My guess is your parents need the extra money the military discount provides because you do not pay for your share of the phone bill. They don't want you to be an authorized user because they don't trust you not to upgrade your phone in ways they can't afford. You are an untrustworthy person by your own admittance. The jig is up, your parents are finally protecting themselves from your financial abuse.

You want a phone where you are the authorized user? Than pay for a plan for yourself. Mommy and Daddy don't owe you a phone.

What's immature and pathetic is that a grown man does not have his own phone account. Seriously grow a pair and stop acting like a little biotch.
