An anonymous reader writes "Today the FTC filed a complaint (PDF) against T-Mobile USA, alleging the carrier made hundreds of millions of dollars from bogus charges placed on customers' bills for unauthorized SMS services. "The FTC alleges that T-Mobile received anywhere from 35 to 40 percent of the total amount charged to consumers for subscriptions for content such as flirting tips, horoscope information or celebrity gossip that typically cost $9.99 per month. According to the FTC's complaint, T-Mobile in some cases continued to bill its customers for these services offered by scammers years after becoming aware of signs that the charges were fraudulent." FTC chairwoman Edith Ramirez said, "It's wrong for a company like T-Mobile to profit from scams against its customers when there were clear warning signs the charges it was imposing were fraudulent.
