Two big cell phone companies operating in Missouri are charged in a lawsuit filed by the Attorney General with overbilling customers for 911 services. The lawsuit filed by Jay Nixon wants to keep the companies from adding fees to customer bills. The lawsuit says the amounts are made to look like taxes, but they’re not. Nextel and Sprint are objects of the lawsuit. Nixon says his lawsuit is designed to get the two companies to be honest in what they’re putting on their bills and to discourage other cell phone companies from starting the practice. The state lawsuit follows the filing of a private lawsuit by customers of the companies.
