Said they were from Nation Insurance Foundation. I've been getting calls from various numbers over the past few days, and, if I pick up, they say they're with the National Insurance Foundation. If I miss the call and try to cal back, it says that it is a non-working number.

got a call from this number which my phone identified as calling from "Sun Valley, CA."  Upon calling back, the automated message said it was Verizon and told me to call back a *different* number.  My phone is on a family plan and I'm not the policy owner, so there's no reason for Verizon to call me.  Most likely a scammer of some sort.

Got a call from this number. Left no message. From what I see above, they are now blocked.. :).

I got a call just now from the same number.  No message - number is now blocked.  :-)

Called me twice today!!!
