Scammers use the bank's reputation to bypass normal caution. When you receive an unsolicited call claiming to be from your bank, always hang up and call the official number from your card or statement, never a number provided in the call itself.

Contact Commonwealth Bank immediately on 13 2221 (their official number) to report the incident and request they monitor your account. If you provided card details, ask them to cancel the card.

What's the difference between this spam call and a legitimate bank contact?
Legitimate Commonwealth Bank calls will never ask for passwords, PINs, or card details. They may reference your account by the last 4 digits if they initiated contact for a legitimate reason. Real bank calls can be verified by hanging up and calling the official number on your card. If 04 0008 6539 or any number called you unsolicited claiming to be your bank, it's almost certainly spam.
