Got a call from this number too. Left partial message saying I'm being sued by the IRS and no further information other than call them back at this number.
Oh no, I'm being sued by the IRS! They left me a message saying that so it must be true! I guess I'll have to burn my house down and flee to Canada before they can get anything from me!
Got a partial recorded message saying I was being sued, but couldn't tell who was suing me. Knew it was a scam because I heard about it before. I know someone (a very trusting person not familiar with the wicked ways of the world) who fell for it and went into a panic. Fortunately we were able to intervene before they sent money.
