what did they say when they called did they tell you you won a grant for 10000

Got a call on my cell from this number today 9/10/14.  Said is was from the IRS and that they are filing a claim against me.  No other information just said to call them at this number.  The caller ID when they called showed up as "unknown wireless caller."  Another scam- be careful.

Just received a call this morning on my cell from the "unknown caller" about the IRS filing a claim against me also.  I know it is a scam, and tried calling the number back, of course it doen't work.

RCVD a call from them to call this number, a guy with Indian accent answered; saying they are a private company working for IRS and I owed $4000 on late taxes, I told him I don't work how I could owe taxes, he said if you think I lie I see you in court.
they are scam, try to scare people and get money from them. report them

Thanks for other posts. Got a call a few days ago and it said it was a call from IRS - Internal Revenue ServiceS (plural).  Also said it was trying to contact us about a lawsuit against us. Early this morning we got a FINAL NOTICE and to call their audit dept. at this number.  So irritating!
