called with an automated IRS msg saying that they were going to sue me. pfft. The IRS knows where I work, i'm sure they'd just garnish the hell out of me.

This is a autodialed recording on my recorder that said they are IRS, that they are filing a lawsuit against me and to return their call at this #.  They wanted $2400 for tax mistakes made on my tax return over a 5 year period.  When I called the # I was threatened with arrest and seizure of all my assets if I did not make a payment today. They had their spiel down pretty convincingly. After listening to this person threatening me with arrest etc. for a few minutes they had me in tears. I told them I was disabled and they said they would cancel the arrest warrant and the court filings. It was then I realized it was a scam.

I am so sorry they did that to you!  If you have access to Google put the number in search ALWAYS before you call back.

A recording telling me the irs had filed a lawsuit against me and to call 209 975-7270

Second FAKE IRS call.  The man sounded like he was from India and was NASTY and said that the lawsuit had been filed and that if we didn't "settle up" we were going to jail.  We told him to come and get us.
