Didnt answer and Googled number, definite a scam, tried to call back and Optus advise the number is disconnected .

cannot call them back, so obviously scammers

Caller: Scammer

Scam call, do not answer

Unsolicited unreturnable call, as others have noted.

Received call from "superannuation advisory service." They asked if I was <name>. I asked "who are you?" They repeated "<name I don't remember> from superannuation advisory service. Are you <name>?" I said "I suspect that this call is a spam or scam call." They said "no, this isn't a scam call." I said "give me some proof that it isn't a scam call." They said "goodbye" and hung up.

My assessment: likely to be a scam call.

Scammer. Time waster. Do not trust.

scamming time wasting bottom fedders

I'm sick of this number calling me every day I will not pick up at all or I will not call them back

Phone record says I have missed two calls 18:23pm. Phone close at hand/volume up. No calls.
Checked here. Thanks for the info. I have Blocked

I recognized that number having called before and as soon as I accept the call, they hang up.

Scammer

Rang back this probable predator/scammer. Message received at my attempt to call back was "the number you have called is not connected".

Don’t pick them
