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.

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!

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 :)
