Total scam.  Computerized voice stated, "The moment you hear this message the IRS is taking action against you for a time-sensitive matter, it is urgent you return our call in order to stop possible seizure of assets"....blah blah blah.
First of all, the IRS will NEVER call you with such a claim.  They send letters via the U.S. mail.    Secondly, caller id displayed "UPR Marlboro MD" instead of IRS or US Government.  Thirdly, I actually work for the IRS and this is a totally bogus call.
Don't fall for this.  Don't call them back.

Attempted to scam a family member.  I called this number over and over and over until he could not take it and blocked my call.  have fun with it, call and do not say anything, just call over and over!  I figure if he is having to answer my call for an hour that is one less person he is scamming.

Voice machine stated to call back for an IRS urgent matter.

I got this too. Must be scam.

Just got "the call" stating IRS is taking action against me. Why dont they just get a real job and stop trying to scam people those lowlife losers!!!
