It IS against the law. Unfortunately the callers are hard core Indian and Pakistani scammer/extortionists who disregard ALL laws. Invest in a call blocker an DO NOT pick up on call numbers you do not recognize.
I got a call from this number. It was a threatening message, pretending it was from the IRS and asking me to call back. IRS would NEVER leave this type of message. I am not calling back.
SCAM!!!!!!!!!!!!! VERY threatening, claim to be from the IRS and if they don't receive money then I will be arrested. When I declined payment the man became rude. Used vulgarity and in what sounded like a foreign accent said, "Americans suck". I immediately disconnected the call.
This number left a message saying I have police charges against me, and that my arrest was in the near future. I called the number back and a very heavy foreign accent answered saying " Hello, Investigation Department, IRS" total fraud!
Left a recording on my phone saying that I have police charges against me and if I don't want to be arrested call them back. This is the scam that has been on the news, just a different number. Will report this number to the police.
