Careflight fund raising. We do contribute. Just didn't recognise this number

This number has rung (I think several times) and there is never anyone there when I pick up.
I am wondering if it is a scammer verifying that our phone number is real.

Third time this week day after day wtf

I called back the number (02) 8064 5019 and reached vm that did not mention the company name

Please do something about this number . I’ve been called about 3rd times and the 3rd times was the first time i answered . im not saying anything also the caller . about 10 seconds and then the scammer maybe ended the call . please do something .

Has rung twice without leaving a message.
Hangs up as I'm answering.
