Who called from 2137108121

Called at 6:00 am sharp-like my own wake up call

Called at 3:38am - rang once.  *69 to find out who called.  Called back to get a recording "press 1 to be removed from the preferred call list".  After the recording, the call disconnected.  This is the 2nd time recently we've had "phantom calls" in the early morning hours.  NOT OKAY.

Called at 4:57 AM.  Number comes from Compton, CA
