Who called from 4067643460

***********************SCAM NUMBER USING A SPOOFED MONTANA AREA CODE*******************
Probably the same scammer that uses 818 764-3459, 818 764-3463 and 818 764-3460 - a home improvement scam.
I called the number back and there is no 764 exchange in Montana.   Previously, we had the 406 area code blocked so their  most recent call did not come through.  Their call was blocked.  
ALL CALLS FROM THE 406 AREA CODE ARE BLOCKED - FOREVER!

Called again - Blocked again!
ALL numbers in the "406" area code are blocked FOREVER!

Interesting...
We receive calls from this number and also from 818 764-3460.
Both numbers are blocked and our phones do not ring.

Called again at 1:58pm 6/18/14.
We have the entire 406 area code blocked.

Called again at 12:44pm - It's nearly 10:30pm and I just saw the call.

Yep - you're still blocked.  They also call from 818 764-3460 and yes, they're also blocked.
