Beware of this New Visa Scam Phone Call!
I groggily answered the ringing phone at 6am, and was alarmed to hear an official-sounding robotic voice. “This is the alert system with Visa (or Mastercard) account services!” It went on to tell me that there were two suspicious charges to my Visa card.

Didn't answer call but a (recorded) voice message was left. Message was truncated so I'm not sure what they were selling - it invited me to press 5 to request an information pack.At this rate, our mobile phones will be as busy with cold callers and scammers as our land-lines. Surprised that so-called regulator does nothing about it.
