This is the Australian Red Cross.

Same as everyone else-never leave message on answering machine-they just hang up Also have a major prob with Dodo number constantly calling - I have a private/silent number and I don' understand how they got it

Same deal here: pick up the phone, instant hang up. Try to call the number: rings then disconnects call. What is the damn point, charity or not?! Poor form. Am in the DNC Register and do not live in NSW anyway.

They called here, a little old lady claiming to be from the Red Cross...

I just got a call from them. They hung up as soon as I answered. Looks like they have restarted calling people.
