Calls from 334-394-3104, 334-394-3074, 334-394-3044 but when I call back get a message that says that number is no longer in service. . .

Same thing -  it started last week.  I got a call from that number three times, but no message left and when I picked up no one there.

This number keeps calling but no one is on the line. Its seems to be a computer just set to keep calling. The callers come in as late as 8:30pm

calls but doesn't leave a message
