It came up as an unknown number for me. I didn't answer and the voice mail they left claimed it was the IRS and that they were going to file a lawsuit against me for fraud. I looked up the number they gave to call back and saw that the Boonville Police Department made a post about a scam going on from that number. I also checked other sites and people have been getting the same call. Block the number if it doesn't come up as Unknown for you.
I got a call telling me that we had fraud charges against us from the IRS and that a warrant had been issued for our arrest. We were told to call this number.
