Scammer who poses as the IRS.  I did not answer. But message stated: "The IRS is filing suit against you.  To get more information regarding this case file, Please call immediately department number (806) 395-2809.  I repeat: (806) 395-2809, Thank You!"  A cursory search on the internet will show this number is a wireless number owned by Verizon.  The US Government (in particular, the IRS) will NEVER call you, especially from a wireless phone. They will always have a landline, HOWEVER,  first they will always send a letter of any action against you, such as an audit.  This is a scam to get your Social Security Number and to extort money from you.  They will state that you owe the IRS $x,xxx.xx amount of money, which you will have to pay (by a certain date) in order to avoid jail time & more monetary penalties.  DON'T BUY INTO THIS LOAD OF CRAP!!!

Don't fall for this IRS Scam: Watch this below CBS News link regarding this type of Scam:

The IRS warned of phone scams in 2013.

   Victims are told they owe money to the IRS and it must be paid promptly through a pre-loaded debit card or wire transfer. If the victim refuses to cooperate, they are then threatened with arrest, deportation or suspension of a business or driver’s license. In many cases, the caller becomes hostile and insulting.

Scam supposedly from IRS

Also received call from this number. Calling attorney general's office. If this is a verizon phone, they can track the owner.

Received a call from this number twice. Both times sent it to voicemail. When I played the voicemail it was not identified as an IRS call. My recording said that it was an emergency call and to return the call for further information.
