Echoing what others have reported. Same message from Heather Gray on my cell number.

If you got this call, rest easy, you're fine -- this is a scam. The IRS will ALWAYS mail you a letter or, if it is serious, a certified letter. They will never initiate contact with a phone call.

Wanted to have some fun with these pricks, so I disabled the outgoing caller ID on my phone and called back. Unfortunately, despite having tried about a hundred times, they're automatically ending the call. I assume they're blocking calls coming in with the caller id info. On second thought, though, that might not have been so clever in case that's one of those numbers that bills you big-time when you call. Anyone know if that's their scam here?

God. I hope not. I called about 15 times, first getting busy signals, then it seemed as if it was picked up, then went into "If you'd like to ....."

I experienced a similar scam deal with "Heather Gray."

5/30/2014 @ 12:50pm – Received message on answering machine & the caller ID read “California (415) 251-2995.”  The message sounded very monotone with no inflections, perhaps an automated (computer generated) voice/call.  The exact message (verbatim) is below:
    “We need you or your retained attorney of records to return the call.  The issue at hand is extremely time sensitive.  I am Officer Heather Gray from Internal Revenue Service and the hotline to my position is (415) 251-2995.  I repeat its (415) 251-2995.  Don’t disregard this message, and do return the call before we take legal allegation against you. Good bye and take care.”
    These criminals need a proof reader for their script, as it has multiple errors:
“Attorney of record” is not plural.  Heather gray from “the” IRS & she would not have a “hotline to her position”, she would have a # to her office & likely an extension.  You cannot take legal “allegation” against someone.  You could take legal “action” against a person, provided you were legitimate.  The closing is not very realistic.  I doubt anyone threatening you, particularly the IRS, would end with, “Good bye and take care.”

recd a vm.. hope they find who is doing this.. VM is automated.

Thank goodness for this forum. I got a call from 415-251-4089 and the automated message told me to call 415-251-2995 or else legal action would come to me.
