This number has been calling my home for many months, is there any information about it? What can we do to stop the calls?

Hung up after voice message kicked in on Jan. 9 at 11:39.

They've been calling here for quite a few months, almost every day. There's never any reply, and its obnoxious.

Called back at night and got a message: "Hello and thank you for calling the General Information line, sorry we missed your call, if you have any questions or concerns please leave your name with area code and phone number at the tone and we will call you back as soon as possible. Thank you and have a great day"

This number called me three times:
2008-01-27 12:00
2008-01-27 11:01
2008-01-27 10:07
No message left. In reverse lookup the number belongs to Call-Net but no further information was found.

I have received numerous calls from this number...very annoying!  I have filed a report with the local police and traced the call.  I received the same recorded message when calling the number back.  Apparently the service provider for the number is Call-Net Communications.
