The sad thing is T-Mobile knows this and are banking on the fact that ATT or Verizon or pretty much any carrier you go to, will eventually pull something similar.

We seem to have reached a point where there is effectively no place you can get decent customer service as an ordinary consumer. It's either, have enough money to sue the crap out of companies, or shut your mouth and endure.

Decades of demonization of regulations has led to a point where the Govt's ability to enforce them is effectively null. With the regulators out of the picture, T-Mobile knows the only real recourse you have is the courts and that a vanishingly small percentage of customers will take that path.

For sure, I don't mean to say it's right. Just that they don't seem to be leveraging non-layman definitions of words. The plan's price will never change really doesn't imply the plan's existence will never change even to a layman, I would think, unless their train of thought is more like paying for this line than paying for this plan which would be problematic. This is in stark contrast to things like lifetime warranties of physical goods (where "lifetime" needs some legal definition) since some physical goods do indeed last virtually forever.
