I get daily calls from this number.  I asked the name of the company and could not understand what the caller says.  Definite overseas accent.  When I ask any other questions, caller hangs up.  When I dial the number back, I receive a message saying the number I have called is not a working number - now how does that work?  I will also call Verizon.  On home phone I can block numbers - wish I could with Verizon on cell phone
