Do consider getting a call blocking device or phone.. You can google them and many are around $50.00 or so.If its a cell phone, some already have call blocking, if not, there are free apps on the web that will work for some. You can google this. If you have a smart phone, there is a free app called call control. Iphones appear to have apps also. Another one is called Mr. Number.

Same caller has used this telephone number as well as 707-666-8607, has called many many times in the past two weeks leaving voice mail messages upwards to three daily.  The voice mail messages have escalated in anger, threat and intimidation in words, phrases and tone.  The caller identifies himself from alternately the FBI or IRS, speaks in a heavy eastern indian accent, sounds like he is reading from a script and leaves a "badge" number. He accuses me of hiding monies and advises me that I will be prosecuted by a federal magistrate if I don't comply with his requests to return his calls.  In the background I can hear other voices and have actually heard another voice using the same phrases; it sounds like he is in a very small room with many people reading the same script. This is a total scam.

Interesting. I got a pop-up message saying to fix a virus on my computer, I had to call this number (although with a 1 in front of it). I guess "Mr. Knight" is expanding his business...

Please disregard my last post. Google led me to the wrong number.
