IRS COLLECTIONS SCAM - A WAY TO IDENTIFY AND COMBAT SUCH DISCONCERTING THREATS:
SIGN UP WITH THE FEDERAL TRADE COMMISSION... http://www.consumer.ftc.gov/scam-alerts
They called from another number to tell me to call this number because the IRS was suing me. I called them back and gave them all of my ex-wive's information.
Voicemail from IRS threatening that they have been trying to reach me and that there is a law suit against me. Called from number 721-452-5697. Told me to call 206-569-4739 to find out more about the case. Scam!
