Appears scam, no message left

Came up scam on mobile

Answered and some person from some Australian survey asking about cost of living.

I have now blocked them. Huge waste of time, only answered because I was told by AGL to expect a call. Phone reply said number is not in service. Scam

Calls often and no message left

Called and no message, seems like scam

Called and didn't leave a message

Called back and female said hello and I hung up
