Have gotten this call a couple time and never answer. Answered today and then my iphone said call was cancelled. I called back and it makes a funny sound and says "the number you have called in not a working number, message CF" if you stay on the line it reapeats the message once again and the 3rd time it say "the number you have called is STILL not a working number" on the 4th repeat it states "I told you this is not a working number". It never disconnects the call and just replays over and over. If you listen closely you can hear laughter in the backgroung of the recording.
