Caller: I do not know

The caller said they wanted to protect me from a couple of fraudulent purchases, wanting to know the expiry date of my credit card.

This call showed as coming from Perth, WA. I missed their call and this time they didn't reach my message bank. I had a call from the same number three days ago, suspected the previous call was a scam attempt and believe this one was an attempted scam also. I wonder if they'll keep trying!

Caller was from visa fraud department wanting to protect me by giving her my card details.

An Indian lady said i have fraudulent purchase from Amazon and want our bank detail to confirm my credit card.

This call showed as coming from Perth, WA. I had missed the call and they reached my voicemail, but left no message. When I called the number back, a recorded Indian woman's voice told me that they were doing a marketing campaign (didn't identify themselves) and that I should leave a message so they could call me back. Not likely! I believe it was an attempted scam call.
