I received an automated message from 202-350-9071 stating that it was the IRS and they were calling about a debt that could cause me to go to jail if not resolved.  When I returned the call someone picked up on the 2nd ring and did answer IRS but when I said what the call said and that I had received nothing in the mail, they said to wait on the letter in the mail and hung up without asking any information in regards to a case.  Very suspicous.

Same just happened to me

That happened to me too and they threatened to freeze my assets and garnish my wages too along with an arrest warrant. You are not alone.

I received a call from this number. He claims to be the IRS and then I was going to have criminal charges filed against me. When I called back they verified an old address that was over two years old. When I refused to give him the last four digits of my social security number he hung up on me. I started thinking if this were really the IRS they would've known my new address because I have sensed filed tax Returns.

I just received which I consider a VERY threating call.  You should take care of the matters right away or face penalties. Really hummm! I may call media and report this also.
