Yes, it was a scam and I was scammed. The caller name is Luke Edward and ask me to transfer the money to Dawit Zeleke's PAYID, pretending as a westpac agent. Well organized team.

Sophisticated WestPac phishing and account transfer fraud call_center hoax (number supplied in a text from "WestPac", but unable to replay to text, as no valid source number), about a temporary 4 digit key. And to call supplied number, "if you didn't authorize this transfer". When you call the number, the HOAX (fake WestPac) protection of your account (the fraud) begins.

Very well spoken manipulator, calm and professional, with a slight UK/Irish accent. I was nearly fooled!

When asked how many accounts you have with the bank, LIE! Mention another number than the real number. If that's accepted, you've revealed the game. And always ask for an indecent number, and you have to call them back. Insistence that the money has to be moved now, will be the other lie. The bank can easily put a temporary freeze on your accounts.
