A man called insisting that I was going to jail someone was coming to my house in 45 mins. Claims I owed IRS which was a lie he didn't speak good english he call us about 3 times today. All a scam .. All he was doing is harrassing us about going to Jail. and I hung up on him,

I got a very disturbing call from 661-759-2960.  They said I needed to take down this number right away and ask for Robert Mathews.  He got very mean with me and said it was urgent.  I laughed and told him "no one tells me what to do" :)
Anyway, I told him never to call me again.  Weirdo

Thanks for alerting me!!

Caller states they work for the US Treasury Dept. and I need to contact them right away in regards to a legal matter. I called the IRS to question this matter and they replied that the Treasury office will not contact anyone regarding legal matters by phone. They also traced the number back to a fraudulent scam that has been going on to take peoples money.

same as reported above from 661-759-2960.  same guy calling me from new number as of today 6/14/2014 - 213-261-0748

•report the incident to the Treasury Inspector General for Tax Administration at 800-366-4484.
•You can also file a complaint with the Federal Trade Commission at FTC.gov. Add "IRS Telephone Scam" to the comments in your complaint.

Do consider maybe getting a call blocking device or phone.. You can google them and many are around $60.00 or so.
