Number has called many times. (name shows unknown in caller ID) Previously, left no message but will sometimes call right back. Today, they left a computerized recorded voice message saying;
"Hello, we have been trying to reach you. This call is officially your final notice from IRS - Internal Reve.....(recorded voice breaks up) The reason for this call is the IR (voice breaks up again) against you. (sounds like filing against you) If you need more information about this case file, please call immediately on our department 202-864-0159."
I did not attempt to return the call. Filed reports w/FTC and IRS.
