they call alot, as soon as i pick up they hang up.

the caller calls frequently, but never leaves a message. I have no idea who this may be????????

They've called before, called again just now.  No message left.  Caller ID says "IL CAL", and the ring on my end is like a double ring.  We haven't signed up for any kind of identifying rings.

This guys calls. : " Patrick?" ( I'm a woman), " Noooo " " Can I talk to him?" " Hes unavailible right now, may I take a message?" " No!"  ( By now my weird o Meter is going off.) " Who -IS- this?" : Click.
Keeps calling back, hangs up when I answer.
I tried dialing the number back. and I get: " Your Number cannot be completed as dialed. Please check the number and dial again"

I started receiving calls from this number on 7/11/07 and have received 5 more calls since then.  They leave no message and when I answer they hang up.  When I call the number I get a recording that says this number is not in service.  Very Annoying!
