I just got a call from scammer pretending to be from Visa, advising me of card fraud on my account. I started to play along, intending to find out what his game was, but we got cut off unexpectedly after a minute or so. Disappointing.
I assume the plan would have been to seek out answers to my personal security questions as held at my bank. He could then call the bank, and request a new card/Pin, or report a change address, whatever. Just guessing, though.
Calling number was displayed as “0000000000”, but a cleverer scammer would change it to a meangful number, like one of the banks contact lines.
Stating the obvious, but worth being aware it’s a scam!
