Caller: Indian scammers

Claimed to be a call about misuse of my debt card overseas from "mastercard Visa fraud office", details of alleged fraud and then directed through a recording of CBA's phone menu to another Indian voice (warning) who had me check my accounts online. I provided a balance figure but no acc ID. then a third person who tried to set up a "sting operation" involving me withdrawing cash they would place in my account! When I refused they hung up.
