Statement from ING spokesperson:

Scammers are sophisticated and professional operators that can trick customers into making transactions they think are legitimate. Whenever we’re alerted to a scam we will do everything within our power to attempt to recover the funds. Sadly, in many instances, a customer may not realise they've been scammed until after funds have gone, at which point it's often impossible to retrieve the funds.

We continuously monitor scams and make regular updates to warn people through our security page (ing.com.au/security), social media channels, app and direct emails to customers. We also use these channels to educate customers and non-customers about different types of scams and how they can protect themselves. Our Stop, Reflect and Protect Guide on our website provides practical advice to help people avoid scams.

If someone thinks they have fallen victim to a scam, we encourage them to call us as soon as possible on our dedicated scams line: 1800 052 743.

Statement from Commonwealth Bank of Australia spokesperson:

CommBank acknowledges the impact frauds and scams are having on customers and the community broadly. Once we have been made aware of a scam or fraud on an account, we work closely with other banks to take action and use our best efforts to recover any funds, while also cooperating with law enforcing agencies.
