The Federal Trade Commission has asked a U.S. district court judge to order a halt to the alleged illegal practices of CTA, a major distributor of prepaid calling cards across the country. In the last quarter of 2007 alone, CTA’s revenue from the sale of cards exceeded $28 million. The FTC charges that CTA misrepresents the number of calling minutes consumers get, fails to disclose that consumers’ cards will be charged whether or not the calls go through, and charges hidden fees.
