Got a 'silent call' from (03) 8908 2896, then about 10 minutes later get a call from this number. Probably spoofed, but Indian guy with lots of call centre background noise claiming to be from a bank account security company (of name he didn't give), he didn't use my name (which I didn't say when I answered) - which all legitimate card/banks will do, I asked him which bank and he listed all the Australian banks and wanted to transfer me to an 'account specialist' - when I asked which account he avoided the question and said "you're using an iphone, right?". I hung up.
