Who called from 7165508259

Called my house 2x, within 20 minutes. Called ID says FBF. Didn't leave a message. When I tried to call back, it wanted me to endter my phone number followed by the # sign, I did, then it wanted me to enter my pin #?

They called again today, I don't answer. Different # than the one that called me, but I found this (http://800notes.com/Phone.aspx/1-847-908-7058) .... same things come up on caller ID - FBF or ACW and it looks like a scam folks.
The numbers that called me were,
716-492-8810 and 716-550-8259.

Continued calls.  Most annoying.  Attempts to pick up only give us "dead air."

Attempts to call back yield busy signals.  As I said, most annoying.

Dead air.  They've called a few times on a Sunday morning.  Political survey?
