Hundreds of thousands of cash-strapped Americans have been targeted by abusive debt collectors operating out of overseas call centers suspected of links to organized crime in India, law enforcement officials told ABC News. The calls are part of a massive scam, one that appears to target struggling Americans -- especially those who have gone online to apply for payday loans. Armed with personal information from those pilfered applications, the threatening callers, who claim to be debt collectors poised to initiate legal action, have managed to pry loose millions of dollars from their victims -- even when the victims never owed money in the first place.
