Exact same as above! I answered and they hung up. I called back and it just beeped like it was a busy line.

Same as above for me.

Called my cell phone (I hardly use and don't give out) twice, just now, 11:18pm Didn't ring long each time, I didn't answer (didn't have time for one thing) and just said missed call.
 Not sure what this is, but usually the odd numbers, late at night are some kind of dating service or chat, and if you press a number to talk to someone you agree to accept the charges for the service.

Called twice just now. Ignored calls.

Rang** sorry..

Called twice and it only wrong once both times. No message left!
