Received a call displaying this phone number an hour ago. The caller pretends to be calling from Commonwealth Bank security in Melbourne and starts the scam by reporting a suspicious international transaction for which they are seeking verification and it's all down hill from there. He was very tenacious so it is unfortunate that I could only afford to waste 23 minutes of his time. Unfortunately, with his work ethic and a moderate, but not strong ability to go "off script" he is probably quite a successful scammer.
