Caller: Common Wealth Bank apparently

Picked up mobile number call on mobile, was a few seconds before someone spoke - but did not know my full name. Said a suspicious transfer on my account to the US, wanted to transfer me to security team to valid cancellation. Lady with Indian ascent, scratchy line. But I don't bank with CBA, just have a VISA card with them. Just hung up, obvious scam. A few seconds later, got another random mobile - same caller, lol
