Who called from 2154368697

I keep missing calls from this number and they never leave a messege.  I looked it up and it says it is from Fremont Michigan.

Idon't answer numbers i don't know

I received a call from this number.  It was a recorded voice which simply said " this call is on behalf of M."

The line went dead.

Same thing happened to me tonight, let the answering machine pick up and it says "this call is on behalf of M" I am going to call the phone company to see if we can get some action started against this # for harrasment.

Received a call from this number a week ago and no one left a messaged. Just got a call today. I answered and someone hung up.
