left a message on the answering machine. Just didn't talk for about 30sec and hung up.

Rang but hung up when the answering machine kicked in & didn't leave a message

Answered call @2.50pm - claiming to be calling on behalf of the World Animal Protection Society (I subscribe to their online newsletter).

Called @6pm 24/9 & again @3pm 25/9 - did not answer call, went to voicemail but no message left either time - pretty sure it would be a call centre

I called back and got a recorded message saying "you were called by World Animal Protection". I am a current supporter of an animal related charity. They possibly are looking for people to donate more.

Someone called me... But idk who

the ring you after you have entered online competions
