The number looks like the official Customer Verification Services Team number (could have been spoofed though?)

This is a new team in the CBA charged with verifying incomes and purposes fpor accounts. They said it was an Anti-Laundering Survey.

Caller: Commonwealth Bank

Recently opened a business profile with CBA and got a call from this number to get information from me. Felt unsure about giving my information over the phone so they gave me alternatives like going into branch. I continued anyway and gave the information they needed and a few hours later my acc was open. Luckily it wasn’t a scam number

Wentao Luang why would you cooperate with the person. They called you, you did not call them. Don't trust anyone who calls you about banking details unless you know them from the bank yourself. Hope you did not lose any funds. Good luck.

Caller: Jed

Told me he was from the commonwealth bank and wanted to update my accounts. Why would the bank call a customer that does not know them. Scammer. I said I'm not with that bank. Hang up on them if they call you.
