No message. I think it’s a scammer.

I agree a bloody Indian scammer trying to see if you answer the phone and then playing a message of a legit business.
Ignore , don’t pick up phone to answer

Caller: (03) 7073 2711

Scam. Called . Left voicemail and full call centre in background

No Message ever left but calls repeatedly.

no message left, keeps calling

Caller: Some solar rebate marketers

These tool bags call and just hang up, call them back and they don’t identify themselves just carry on like you know who they are. They’re calling me because the previous owner of my phone number (10 years ago mind you) just gave hers out to anyone and everyone
