Received an automated voice call, caller ID:  VOXBONE  SA  #703 542-1703
Claims to be from IRS and that I failed to sign and return a registered letter sent to me.
A lawsuit to be prosecuted against my name without need of trial controlled by IRS HQ in Washington DC, unless I respond by calling 703 542-1703.
WHAT A SCAM, not even going to entertain, but am blocking the above number along with 703 542-1704.
Got into the habit of blocking scam numbers as I get them. If not, they keep calling all hours of the day and night.

received the same call, they called my cell phone 5 times today finally I decided to answer. The IRS will never call you they will mail you or show up to your home. Such a horrible scam. Few days ago cousin received same call and the representative called her a b***h when she wouldnt give her information to them. Clearly not the IRS

It went to voicemail and I received 2 calls on 5/15/2015 from this number and I knew it was a scam

Just happened to me!!! They were berating me and said I owed money. Said they sent certified letters and I didn't respond!! Said they were congrats to arrest me and seize all bank accounts.  Total scam. Blocking this number!!! Go to www.tigta.gov and file complaint with the IRS

This guy called and said he's from the IRS. Clearly not but did t ask for anything. I figured he was setting me up for a later call. Saying its a courtesy call from the IRS and they are coming to arrest me.

Idiots. Do t believe them.
