I keep getting calls from this number.  The caller ID says unknown name.  I let the answering machine pick up, but they never leave a message.  This happens two to three times a week.

I keep getting calls from this number and I'm not able to block it because the caller ID is not giving the actual number.  When I call this number back I get a message that says "number is not allocated".

Calls from this number actually from the Phillipines supposedly for health company survey, they ask a lot of personal questions about newest car, etc, terminated the call, told them to move on to next on list. We are on no call list.
