I don't know this number and I am plagued by spam callers. This one called at 3pm and I didn't answer, didn't leave a message, I wasn't expecting a call and I didn't call back - my policy is only to answer phone calls whose number I recognise or at a time I have agreed to receive a call. I suspect this as spam, not least as the number originated from another State.

Picked up and said nothing, call disco. Called back, msg bank adv number not connected.
Call not from Sydney. Fraud call.

Caller: Suspicious

I received two missed calls from this number. I returned the call and it had a recorded message that said “This number is not in use.” Then it automatically hung up on me. Very suspicious.
