Received a call to my landline, and my phone announced this local number, (02) 6556 1041, so I answered. It was a recorded voice saying "You have a problem with your Visa Card...." at which point I hung up.
I then called the number back. It was answered by a woman and I asked if she had anything to do with Visa. I explained to her that I'd just received a call from her number, and it was being used by a scammer (but she suspected I was a scammer, and hung up!)
It looks like her number has been commandeered by scammers, and she needs to be informed about this by someone she will believe! I have informed Scamwatch
