T Mobile / harassing phone calls

Let me ask you, if a child decides that while no one is home they should make some crank calls does a phone company have the right to turn off the parents service? Hopefully you have enough sense to say "no". A phone company has no ability to tell who is using the service or what the intention of a person's call to someone else is. It's not possible for a company to just jump ship on fcc regulations on who is authorized to call in to make changes to an account either. So, in your example there is nothing a phone company can possibly do, so it's really unfair of you to drag t-mobile through the mud, just because you find yourself in a awful position.
