writes "Bloomberg News is reporting (http://www.bloomberg.com/news/2012-03-22/at-t-accused-of-improperly-billing-u-s-program-for-deaf-1-.html) that AT&T got more than $16 million from the US government to run Telecommunications Relay Services, intended to help the hearing- and speech-impaired. However, as "many as 95 percent of the calls in AT&T’s hearing- impaired program were made by people outside the U.S. attempting to defraud merchants through the use of stolen credit cards, counterfeit checks and money orders".
According to the US Department of Justice (DOJ), "AT&T in 2004, after getting complaints from merchants, determined the Internet Protocol addresses of 10 of the top 12 users of the service were abroad, primarily in Lagos, Nigeria"
The DOJ intervened in the whistle-blower lawsuit Lyttle v. AT&T Communications of Pennsylvania, 10-01376, U.S. District Court, Western District of Pennsylvania (Pittsburgh). The DOJ is seeking triple damages from AT&T"Link to Original Source
