Please explain to me how you arrest someone in Asia, or Africa? Foreign criminals using high speed internet, voip, a few dollars in software are calling Americans for all sorts of extortion scams. So now what? Oh! Let me tell you: (1) DO NOT call back a number you do not know (2) No voice mail, no worries. (3) Check ALL numbers on line FIRST. If the number leads you to 800 notes, READ what is writen here. (4) Know your civil rights. Debt is civil, not criminal. LEARN what debt collector's in your State can, & cannot do. Due diligence!

Got the call and told them they were a scam! even before I read this then went on line and found this.  They said you know you are being recorded and hung up.

Got multiple calls from a person identifying themselves as Chris Milo from the IRS. He left a number of 571-207-0690. We recognize that this individual and their team are fraudulent.

DO NOT CONTACT THERE EVIL SCAM PEOPLE. tHERE'ER PRO'S. DON'T GIVE THEM ANY INFO ABOUT YOUR SELF. Debt, SSN#, or members of your family.  Got called 2day by a Sean Stiffler claiming 2B from IRS. We've been going through this since 7feb2014. Thc called @ 5:45am. A man claiming 2b a Mark Anderson, with a thick India accent, claiming 2b IRS and my spouse had reported income few few years back. This should have been a red flag 2me since my spouse hasn't worked for seven years now. The was no income.  I got scared when he listed the things that going to happen to my spouse with immediately freezing of bank accounts, freezing of asset, seizing of passport, up to $25,000 in fine, and court cost...etc and the like the Sheriff was going to come and arrest me and arraign me right now.  They knew all the right things to say, when to sound mean. I received a call from 571 207 0690 threatening me from IRS penalty and tax evasion... The person identified himself as Kevin Brown and said I need to pay $3600 by end of the day by wire transfer. Sad 2say I piad  up  to $2100 b4 I paid attention 2the red flages. Heck I was on the phone, my cell, with an FBI agent trying 2report what was happening. I told the evil man,someone claiming 2b a Mark Anderson, that we'er hangng up now. With out even a heart beat he clain " fine if that is what you want to do. Your want to take your chances in court" ECT" I am just trying help you out. Just say you want your money refunded and we'll file tax evasion charges and you take your chance in court." etc etc etc. I was enough 2make question.

They are criminal extortionists located in either India or Pakistan.  Their governments are not going to do anything and our government can't.  So. You have to protect yourself.  Never give personal information or send money to people you don't know.  This is especially true if you are talking to someone with a strong Indian accent that uses a Westernized name.
