Received a call from 303 209-9314 marked as "Unknown Caller".  I didn't answer since I don't know them. 303 is a Colorado Area Code.

Called twice, will not leave a message!!  Not worth wasting my time answering the phone!!

received a call from this  number  on 10/26/15 about 8 PM in the evening. Number unknown to me, even though the area code was local, likely that is spoofed as an incentive to get people to pick up.
Caller ID stated 'No Name Sent' a giveaway that it's junk. Did not allow my machine to pickup but blocked it in mid-ring since I knew it was certainly a spam/scam or robocall.

Called five times in half an hour!

Called at least 10 times today. Last calls were 3-5 minutes apart! Finally answered and it was Freedom Partners. I just hung up.
