Called my cell phone at 10:30 at night....left no message and when I called back, the call can't go through...

dam, woke me up 1 hour & 15 minutes before I had to get up. Nothing is worse then being woke up before the alarm clock is set to go off for nothing by a prank call that just hangs up on me. Tried to call back, call could not be completed.

Called 0312EST. One ring, No message.

Called my house at 11:51 pm.  No message.  Too late to be calling.

Called at 4:52 p.m. yesterday.  Hung up before the phone rang enough times to leave a message.  Later about 10:30 p.m. got another call, but from 360-722-5972.  About 3 a.m. this morning got a third call from 360-722-5981.  Since all three calls came within a 12 hour period, I believe the calls are from the same source.  Each time my caller i.d. showed only the number.
