Claimed to be from the IRS and that they would sue me. The IRS warns that they will not call you but notify you by mail. Of all the times I have been contacted by the IRS, there was never an office in Washington State. The IRS warn people to not call the number back but report them to stop the robocalling scam.

Auto message that IRS was coming to arrest me if I did not call back. DO NOT CALL A SCAM per IRS

Get the same call about 3 or 4 times a day. Never leaves a name of a person to contact, just a number saying to call about more information on this case.

These people are committing a federal crime by impersonating the IRS. If they contact you, file a complaint. https://www.irs.gov/uac/report-phishing

Received a call and they left a prerecorded message to all the office at that number. When I called back a woman answered but I couldn't understand what she said. I asked who I was calling and she said, "The IRS."
