T-Mobile tries to convince customer to drop price hike-related FCC complaint, fails spectacularly

I was curious but only enough to get it summarized:

T-Mobile is trying to get customers who filed FCC complaints about recent price hikes to drop those complaints. However, at least one customer, "mjsztainbok," is refusing to back down, citing T-Mobile's broken promises and misleading claims. T-Mobile's "Un-contract" and "Price Lock" guarantees appear to have been violated, with the company's explanations being unsatisfactory. Customers feel cheated, and T-Mobile could face legal and regulatory troubles, including a potential class action lawsuit, over false advertising. The issue is unlikely to go away anytime soon for the "Re-carrier."
