T-Mobile executives say they are "dumbfounded" by the charges, which were outlined in a recent Wall Street Journal article.
John Legere, T-Mobile's rambunctious CEO, fired back Thursday at recent claims that his company is throttling the connection speeds of customers who use the carrier's new "Binge On" streaming option. The Binge On program allows users to stream content from selected music and video sites, without counting it against their monthly data usage.
