Caller: I don't know

Number called and left a "message".

The "Message" was just a garbled fragment that sounded foreign, then they hung up.

Sounded like a fraud call centre in the background. Sounded nothing like a real call centre or real message. Please be VERY suspicious about this number if it calls you, until someone trusted verifies it.
I called back twice to verify and no-one ever answered the phone.

My personal view is that it has been taken by Scammers as at May 2023.
Cheers all.

Unknown caller because their call didn't ring through....they were intercepted by my Telstra Call Guardian, who instructed them that they MUST announce themselves & press # in order to be put through to me....they didn't....another scammer bites the dust, & I wasn't inconvenienced one bit...phone didn't ring...... thanks to Telstra Call Guardian....now they are permanently blocked....

Scam - heavy accent purporting to be from a travel company telling me I filled out a form 'somewhere' 12-24 months ago....able to cite my address (which is a worry) but tried to reassure me that it was fine that I wouldn't remember doing it. Didn't wait to see what wonderful prize I'd won or refund I was due...
