Who called from 4121892472

When I pick up it just beeps and disconnects. When I try to call back it says I have reached a Verizon number that doesn't exist. No idea.

called this morning caller ID sais Pennsylvania hung up on answering machine

Called me last week and again just now.  Doesn't leave a message, and I wasn't able to take the call either time.

This number calls me all the time and hangs up before I can answer. Never leaves a message and when I call it back it says call cannot be completed check the number and dial again..weird

This # just called I picked up the phone and a lady said good bye. I called back and the operator said that # is disconnected very strange.
