Who called from 3475605677

I received the same exact message today. What a crock.  It's would only contact you by official mail. Tried calling number back. Nothing but dead silence

Got the same call with an automated voice. Decided peek down the rabbit hole so I called back. Got an Indian sounding fellow who answered "Internal Revenue Service, how may I help you?" So it seems they're stepping up their spoof efforts.

Saying calling from IRS

yeah they called me and left a message claiming the same thing...it was good for a laugh

Number called saying they are the IRS and filling a lawsuit against me.
