Received a NY area code number and as I didn't recognize it, I allowed it to go to voice mail. I got 1/2 the message, starting with "magistrate or grand jury . . .", so this must be a recording or an idiot that spoke over the recording inviting people to leave a message. I'm guessing subcontinental Asia is the origin of this call. The accent was heavily influenced by British English.
Same thing but only part came through voice mail. When I called back, connection was horrible. Gave first name and he had my maiden (married not a year).
Actually the IRS is working to combat these kinds of scam. But there isn't much that can be done currently since the callers are located in India and Pakistan and outside the reach of US law. Ignore and block the calls.
