I didn't answer this number when I saw it displayed.
Have been receiving many similar calls another being (02) 8823 3096.

Hung up when I called. I called the number back and it was a charity organisation of some sort.

same as rest, why call then hang up? I usually filter numbers I don't know but just picked up as was near phone and it was a Sydney number and thought was number I knew.
