SCAM! This is a total phishing scam. Do not answer, if you do, insult them vigorously. I got a pre-recorded computer generated message. No accident these calls come just before April 15. My caller ID said 202-239-0191 Washington, D.C.
I received a call from this number today saying I was under investigation for tax fraud and my property will be taken. Caller name was Kimberly Gray from the IRS.
