threats that irs is suing me

9/11/15 11:53 PDT  Not the first call of this sort.  A very Indian or Pakistani accent claiming to be David Grey and saying I need to call back to avoid prosecution by the IRS.  Knew right off the bat that this was a scam call.  Where the hell is Gustine  CA.  That was the ID.  Background was an echo chamber noise.  These are not crank or prank calls.  They are outright fraud and we need to be able to shut them down for good!!  I'm sorry that I am old school and refuse to bow to these crooks.  Simply refuse to answer the phone and then report here all of these frauds.

9/11/15 12:56 PDT  Second call from this crap number in about an hour.  Last time left threatening message about a suit pending against me.  This time,  no message.  Am about to add to blocked list.  Fed up to the teeth with this garbage.  Have a feeling now may be calling from prison since area code includes Lodi, CA

Received call from this number at approx 3:50 PM.  Don't know anyone in Gustine, CA (which is over in the San Joaquin Valley, if memory serves me) so just disconnected the call.  Per the above calls a couple of months ago I received a call from a person  with a heavy east Indian accent, who very officiously said I was under criminal investigation.  When he asked  me to confirm who I am, told him I was Elizabeth Windsor (Queen of England) and told him he was a sorry piece of humanity and not to call me again.  He had called me five times in succession - because I had disconnected each of the immediately preceding calls.  At least the creep didn't call me at midnight. Gotta get a call blocker that works.

I received a call from this number twice & am sure it's a scam so do not wish to be bothered by him.
