this phone number (206 488 6994) has called my cell phone twice within a few hours leaving a message that " This is a call from the IRS regarding a lawsuit they have filed against you."
Received 3 similar messages today from this number. The IRS does not contact you by phone. They only contact you by registered or certified mail. Do not fall for this scam.
I called them back, a woman answered, and when I stated that "The IRS doesn't contact via telephone, can you tell me who I am?" she immediately hung up.
