Ignored. This one left a computerized male voice message saying I owe the IRS money. Love these. Get a life you creeps. I've had another one from same area code calling to for another thing.
"This from the IRS. The nature and the purpose of this call is to inform you
that we have received a legal petition notice concerning a tax fraud against
you. So before this matter goes to the Federal claims court house or before
you get arrested. Please call immediately on our department number
206-489-0122. Make sure you call us as soon as possible."
did not respond but highly likely to be fraudulent
