Got a call 9 am today.  I never answer calls showing "unknown name".  Don't know, don't care, but these calls are still aggravating.  If you get to many of these calls, you may want to invest in a whistle.  Next time they call answer & blow,  real loud.  Another tactic is to answer the phone, don't say anything,  put down the receiver, and go about your business.  Guaranteed they won't call back.

Received a few calls on a daily basis from this number, asking for someone.

calls every day but no answer
