Caller: Male caller

This call showed simply as coming from Australia. When I answered there was a delay of some seconds, followed by sounds of indistinct voices which sounded like a call centre, then a male voice (with an Indian accent) told me that he was from the security department of the Commonwealth Bank and that someone had been using my bank card in the United States to make some purchases. He then asked me if I thought the transactions may have been fraudulent and I replied that the transactions were OK and I was quite happy about it. There was a short period of silence, then the call was terminated (from the other end). Obviously a scam.
