206-462-5040

This number called saying he was from IRS. Any suggestions on how to handle it?

The IRS will not call you. They send letters via US Mail. The IRS won't ask you to pay in i-Tunes cards. The IRS will not wish you "good luck as the situation unfolds". Trust yourself and your instincts - do not let a bully intimidate you with threats that are nothing but hot air. This is a SCAM. Do not answer calls you don't know and never call them back.

Consider getting a call blocking device (or app for your cell phone)-they're available online and start around $50 or so. https://800notes.com/nb/search?q=call+blockers

Got the same guy but a 971 area code

I have been getting the same call 3 times a day for 2 weeks now, he says he is Robert Edwin and that a no nail warrant has been issued for my tax audit! Lol! Do not give this guy any information the real Robert Edwin Davis is at least 90 something years old or more than likely dead by now and no longer works for the IRS! WHAT A SHAME
