(NBC) - T-Mobile is sued by the Federal Trade Commission.
The FTC says the carrier cashed in big by hitting customers with hundreds of millions of dollars in bogus charges over the past several years.
The charges were from text message subscriptions for things like flirting tips, horoscopes, and celebrity gossip.
Those charges frequently were not authorized by customers, and as many as 40 percent asked for refunds.
T-Mobile CEO fired back, calling the FTC complaint "sensationalized, unfounded, and without merit."
