Who called from 5675695478

Call I answered no one spoke I tried to call it back and said it was not in service

The same thing happened to me.

How do we stop these harrassing calls.

same here..

Received call from 567-569-5478 at 2:36 pm 9/28/09.  Caller hung up when I answered.  Called back and was informed "the call cannot be completed as dialed".

ask yourself if it's a collection agency confirming your phone number so an agent can call later.
