Did you really need to "Ask Slashdot" about this? If T-Mobile's CSRs hung up on you, then you march down to the nearest store and let loose on the first salesperson you see. You *should* have gotten the names of those CSRs (I always make a point of writing down the person's name when I call any kind of support) to give to whoever it is that finally *does* take your complaint. Either they or their manager should be fired.
And, once you get this issue resolved, leave T-Mobile.
