Caller says I am being sued by IRS

Said being sued by IRS, not likely

3rd call in two days,all from different numbers, same recording,same voice, telling me IRS has filed suit against me. What a scam.

Official IRS Government site detailing this scam and providing links to report it:
http://www.irs.gov/uac/Newsroom/IRS-Warns-of-Pervasive-Telephone-Scam

If you feel you SSN has been compromised, in addition to putting a fraud alert at the 3 credit bureaus, you may want to notify the IRS.  Here is the link, fill out the proper form (probably 14039):
