Recorded voice that a transaction of $1299 was made on my debit card. Press 1 if I didn't authorise the transaction. I don't have a debit card! Nice try.

This was an automated call saying it was ANZ and there was an unauthorised transaction on my debit card - and I'm not an ANZ customer :)

Caller: 6255 9951

He said that a transaction of $1xxx from my card. Scam caller

Caller: Scam

Scam caller

They called me, I didn't answer then they called back immediately and I answered but they hung up straight away. I blocked the number

I never really heard what he was saying, but I did hear something about a security company

Recorded voice saying from Commonwealth Bank and a transaction had been made on my debit card - press 1 if I didn't authorise it. - I don't have a debit card lol

Caller: (08) 6255 9954

This was initially an automated call stating a suspicious transaction of $1200 has appeared on my card. Press 1 if you did not authorise. Press 2 if you authorised.
1 led to an operator (named Charles) who sent a OTP (one time pin) to my mobile from Amazon. I did not provide ANY details. He seemed to have enough to sound credible BUT I did a check at the same time and sent a chat message to the ANZ bank who confirmed, this is NOT coming from them. Be CAREFUL!

Thank you everyone who posted before me. It helped!
