Calls me, leaves no message.  When I call it, it rings once then hangs up.

calls me twice  while I'm in a important meeting.  when I call back  it rings one and hands up.   why you do did too me!?!

Keeps calling but doesn't leave a message. Try to call back and get hung up on

Same here also. Got 4 phone calls.

This number calls and does the same to my number.  Calls and does not leave message.  When answer, doesn't respond.  When I call back, it hangs up.  I don't have my name recorded, so not sure if calling to verify identity.  Calls occur 3-4 times/day sometimes more often.  Just started receiving on new phone cell service line.
