I get calls from this number but never anyone on the other end.

If they are calling your mobile, set up 'reject' call

I got this at 11.35am = I missed it but they didn't leave a message. glad I read this! I won't be calling back.

Hangs up when answered. So annoying. Same as Sam - when i rang the number a recorded message said it was a generic number for not for profit charities & exempt from do not call register.

I have been receiving calls weekly from this number and when I answer it hangs up straight away. I just called the number back and a recoded message advises it is a not for profit charity and they are excempt from the do not call register. That really annoys me! So often this happens these days with charities.

Yep WTF ? six times in a week. Same with this number (02) 9814 7428 nine F'n times.

WTF!!!

I just had one too. Same number, hang up when I answered.
