Google AI search says
"The phone number (02) 9098 2060 belongs to KLW Group Pty Ltd. KLW Group Pty Ltd is a company that provides tax and accounting services."
but this number does not match the number on KLW Group Website and no reason I know of for KLW Group to be calling me repeatedly but leaving no message to inform me of why they are trying to contact me. Screams scam to me.

Said it was Paypal security

Canvassing for credit card authorisation … of an unknown “transaction”.

Scam caller, left msg saying I had important documents to sign in Chinese or english. My pH had luckily flagged it so I didn't answer, be safe team!

Says it's Comm Bank, suspicious transaction recorded message, no security alert on app so very suspicious.

Caller: Scammer

Pretending to be CBA. Automated call. Blocked number after it hung up on my silence.
