This is definitely a scam based out of New York but coordinated in India. These guys are low life brown people. The IRS doesn't call or leave messages.
I got the same message when i called back i dindnt know anything so i gave them my name and my zip code ...... do you guys think they would do something bad agains me?? ...because they got that information!!
They called me.... claimed it was IRS lawsuit against me. I know better... IRS would communicate in WRITING.
I did NOT confirm my name I only asked them to remove my cell # from their calling list - then they asked :Ma'am may I ask what is your religion? Are you Muslim?
I told them that I declined to answer any questions not related to removing my number from their calling list.
Got the call them and say ok what is this. They said must pay taxes I said ok so I said I don't have credit card but cash, they we can meet I said ok. When I said they San come to my office they ask where I said the federal building of the FBI. They hanged up.
