I received a call from this number at 6:00 am this morning. I did not get to the phone in time before it stopped ringing. No voice mail message was left. I called the number that showed up on my caller ID and I received a message indicating that the number was not in service.  A half hour later I received another call from a different and incomplete phone number (4-4004) and the caller ID indicated 'caller unknown'. Again, no message left.  Strange.  I do not owe any money to anybody, so if it a bill collector they have the wrong person.
