Female with foreign accent called claiming to be from Visa and Mastercard Investigation Dept (3rd call like this in 7 days). I asked questions. Where are you calling from? said Australia & address is 50 Bridge St, Sydney. I asked for a number to call back on - she said it is on the back of my card, then something about calling 101 or 102??? The line was crackly, intermittent & her English was hard to understand. I asked her name and she said 'Anna Albert'. I asked her for the last 4 digits of the card she claimed there was suspicious activity on, but she made some lame excuse about not being able to do this. I told her I knew it was a scam call and she hung up.
