Today I got a call from this number too. Same description as everyone else's here. A guy with Indian accent left a voice message claiming there is security issue with immigration bureau threatening legal action if we don't reply his call.
In Sept 2013, these same [***] succeeded in chaeting (USD 4,000) an elderly Indian lady (homemaker) in DE, USA who had been recently widowed and was rather vulnerable. They asked her to wire the funds immediately via WU, or else would be arrested. Unfortunately the ladey fell for it and departed with her money to these scammers.
Got a phone call from a person claiming to be an IRS agent. Justin Johnson had an heavy Indian accent, said that he was from the IRS San Francisco office. Claimed there was a mi-calculation of taxes due. Had me write down a case number 658730. Threatened a lawsuit. SCAM. Impersonation of a federal agent is a crime.
I received a call from same phone and he said his name was Dave Smith from IRS. I thought no one calls from IRS and
first they send you a written notice and they won't call you.
Same thing as the rest, threatened to have my wife arrested for some sort of income tax fraud, wanted to know my lawer and fax number, when I asked him for info, none. Just insisted she was going to jail unless I resolved this now. After many minutes of playing dump and asking questions, he got mad and hung up. Scammers all the way. Reported this to the Irs, they know about it as well as the federal communications people. They are from overseas and hard to track was the answer I got.
