Caller: Extremely Suspicious "Commbank security" call

Had a phone call from this number to my wife, claiming to be "Commbank security department". I answered call bcos my wife was on a online class. There was background noise and wasn't the typical professional style so it sounded very fishy and sus. I kept asking some questions and the woman got very angry and was rude, told me "oh shut up" before she hung up the call. Informed the bank, be on the lookout bcos this might be one attempt of a larger scamming op.
