I recently received a call from 215-689-7431. It came up on my caller I.D. as unknown name. I answered it and nobody was saying anything so I hung up. I tried calling the back and I got a fax machine.

every day call from fax global - no msg.
when phone answered said it was a 'chimney' service.
asked that they not call again - they hung up.

Keep getting unwanted cals with no voice on the other end.  Very frustrating....
