Caller: Citibank Credit Card Security

Received a phone call and then a voicemail as I didn't answer. Said they were from Citibank Credit Card Security on behalf of Bank of Queensland. Was suspicious but after reading some other comments, rang Bank of Queensland on the number on the back of my card and it is Legitimate.
There has been suspicious activity and they are investing

Caller: Said they were from Citibank Credit Card dept

I got a call- said was from Citybank , but I didn’t answer and this was followed by a voicemail saying there was suspicious activity on my Bank of Queensland credit card account - and told me to ring 1300 441 897 or (02) 8027 2000.

scam call

Claimed to be from Bank of Queensland. Knew my full name! Thought it was legit, they told me to cancel my cards. I was silent for a bit, couldn't quite understand her, when she asked if I could hear her, I told her I couldn't only the children in the background, she hung up!

Caller: Claimed to be Coles MasterCard fraud

Scam!
When I said I would ring back direct she said to call number on back of card.
Obviously spoofed the number as when I called direct there was no recording of me being called. Fraud department said this is increasing as people often think the caller is genuine if they say please call the number on the back of the card.

Caller: Citibank Credit Card Security

Verified: REAL
.
I missed a call from this number. There was an automated message left saying it was from Citibank Card Security and asked me to call back on either of 2 other numbers.
.
I got a general number to call off Citibank's website, and rang that instead.
.
They put me through to Citibank's Credit Card security team.
They CONFIRMED that they'd called me. A merchant notified them of a data breach. I'd purchased from the merchant back in May 2019 (It's now Nov 2021) and Citibank wanted to cancel the card and send me a new one.

Caller: (02) 8027 2000

Missed call - said it was from Qantas Mony and to ring back on a 1300 number in relation to suspicious transactions. The 1300 no was not contact number listed for the credit card on the App.

Caller: Bank security fraud team

You need to call your card issuer directly. Not the number that called you. It is a call centre number that is one way calls only.

Caller: Coles MasterCard Security Team

LEGITAMITE. Received a call stating the from Coles Mastercard Security Team. They said they had info that my card details had been compromised. The accent was not very clear. They wanted my permission to block my card and transfer the details to a new card. I was not convinced and would not agree nor give her any info. She was polite and said to call the number on the back of my card if I felt uncertain about the call. We ended the call.
I called the number on the back of my card and they confirmed their security team had called and left a note on my file. Apparently my card details were picked up from an illegal terminal scanner and they want to cancel my card and issue a new one. This is what I did and it is all good now. No issues. They did a great job and I am very grateful that I have this service to assist me before being shocked by illegal transactions. All happy here :) Its legit. Call your card issuer direct if you are unsure. Dont just post a comment here saying scam without following thru further.

Caller: Coles Mastercard (not!)
