Who called from 2138141484

This number has called me repeatedly over the last 2 weeks, have not left a voice mail or anything. who is it?

I get calls every day from this number - but no message.  I tried to call back and I get a message to call back during regular business hours even though I received the call only seconds before!!

get the same thing -calls every day, complete silence on the other end. I have never called it back. No message is ever left...

Ditto the other posts re daily silent calls--calling back immediately ALWAYS get the recorded message to 'call back during office hours.'  There must be SOME WAY to block these???

calls my number everyday - leaves no message
