According to Federal Regulators, T-Mobile customers have a reason to question charges found on their bills. T-Mobile is being sued by Federal Regulators over adding charges to its customers that customers never authorized. The bogus charges were for items such as horoscope texts and pricey ringtones. The Federal Trade Commission says the charges span from 2009 through last December. The commission also says T-Mobile received hundreds of millions of dollars. T-Mobile is dismissing the lawsuit.
