I did not answer but they left a message that said they were calling from the IRS and I am being sued by the IRS. They have called several times before but I didn't answer and they said this would be my final warning, however, I bet they keep calling.
Yes, I received a call from this number, 206-258-7964 and an unknown company also, telling me that I was being sued by the IRS. After searching the Web for this number, and it was not identified, it clearly cannot be the IRS. They would only use known and published phone numbers.
Area code 206 is listed in Seattle, Washington. Caller left a message they were the IRS looking to collect unpaid taxes. IRS does not call, they send letters.
