No one on the line.

A recorded message called my home stating that the IRS was flinging a lawsuit against me. I was told to dial this number for more information. When I called a man (with a foreign accent) answered, "IRS, how may I help you?"

Same story, claimed it was the IRS .. (IRS does not call you ! - you'll get a registered letter from them.)
They claim if you send them money they'll drop the charges ...  another scam ...
