I just received a call today (on my answering machine). Said it was the Fraud Department of the IRS and that there was tax fraud against my name, and call soon to avoid a warrant for my arrest.
Basically same call as everyone else on the post. I would suggest you keep them on the phone for a few minutes then introduce yourself as Joe blow from the FBI fraud identification unit, tell them you have tracked their call, you have a GPS lock on their location, and the sheriff will be there in 45 minutes or less. Let them worry about that for awhile.
I have got this call twice in the last week same guy "Jason oconner" with the "IRS"! Irs does not call u they send a certified mail. I different number called me last month. The IRS phone callers are scammers!
