Didn't answer incoming call from this number.
Called back and received "number not in service" recording.
Probable scammer.

Caller: (03) 9112 5863

It is an annoying call center trying to flog you Energy companies. Hardly any English, keep ringing if you do not answer and if you do answer and ask them to stop it only encourages them to keep on ringing.
Difficult to block as the first 4 numbers do not change, but the last 4 numbers change.

Caller: I don’t know

Keep getting missed calls from this number. No VM. Seems like a scammer

Caller: 9112 5863

I’ve received 5 calls from this number over two days. Called back and recording says number not in service = scam! Should be a way on mobiles to disconnect their call if they keep redialing you if you block them.

I called back the number (03) 9112 5863 and reached vm that did not mention the company name
