Who called from 6783733680

Called me 3-2-2016 @ 7:15pm.in So. Dakota. I didn't answer and no message was left.

Calls at midnight

Called 259am, didn't answer.  Voice mail was 55 seconds of silence.

Got a call from this number at 1am, was half asleep so tried to call it back, got that it had no voice mail set up. Wouldn't have called back but was afraid it was an emergency at that time of night, and didn't really look at the number before I called back.

Got a call from this number at 12:45 in the morning. No one there when I answered, tried to return the call and it didn't ever ring, just went straight to the message, "the number you are calling has a voicemail that hasn't been set up."
