When answered just hung up

Didn't answer, when calling back automated message advised it was from paretophone.com on behalf of a charity and to email at callingenquiries @ paretophone.com to stop calls.

Will block number and send an email.

Spam caller - when I called back an AUstralian voice message saying it is a third party on behalf of a charity I once supported. Beware.

Hangs up when you answer. Spam

Kept calling, called back and straight to answer phone. Blocked.

Caller: On behalf of a charity

They immediately hung up when I answered, when I called them back and automated message identified themself as a third party which speaks on behalf of "a charity you support or one you have supported in the past"
