Unrecognized number.  Blocked for the future.  Scumbags.

New number. No info.

No message just hang up.
Just started calling everyone today? Interesting

Received a call from this number back on 3/3/17 (clearing out my "missed calls" log today).
They left no message and since other people here have reported receiving an unsolicited calls from them, I have to assume they are "Call Blocking" worthy.
