Well, do you care enough to take your business elsewhere? That's really the last-ditch way for you to have any voice on this.

For whatever it's worth, I left them recently for this very reason (your choice is yours, mine is mine, no preaching or judgement here either) – I ended up having a few minute conversation with the confused (but nice) call rep who didn't understand what they were doing but seemed to empathize as I explained it. Ultimately, will my explanation matter? Probably not, but it was all the power I felt I had, beyond cutting them off from my monthly payments.

While still not trustworthy in my book, t-mobile is definitely an upgrade, at least in this regard.
