Dont know, didn't pick up the phone. No VM left. Possibly scam based on the comments.

This number is a scam as Coles doesn't have this number in their system and there is no registration for recent call to my number.

suspected spam call.

When I answered (showed as from Sydney area) it was an automated robotic message "hold the line please, we have no one to answer your call".
I hung up

I didn't answer and no message left.
Don't think it's Coles Financial Services, as on their website, the phone numbers are "1300 306 397 OR if you're overseas ((02) 8288 2890".

In the morning I got a text saying NAB has changed their system,
In the afternoon a got a call from this number from showing from Sydney, it’s a scam like others had reported.

Second call from this number. I forgot to block it. No message either time so assume scam

Answered call noone spoke back I hung up I suspect it is a scam call

Caller: (02) 9296 5698

I find it very strange if this is a legit call, why they don't leave some sort of voice mail but hang up. Sorry this caller has been blocked.

Caller: Claimed to be from NAB

Asian woman knew my name and wanted something to do with my account. Just told her don't have one and hung up and blocked caller

Asian sounding female claiming to be from NAB bank. Knew my first name but wanted surname and address.
