Caller: A scammer who said they were from NAB bank

this person had an Indian sounding accent and said he was from the NAB bank and there was a transaction to and overseas company for $754 . he asked if i made the transaction and said someone has hacked my account. the said he would stop this payment and reset my online banking and told me not to use it for 24 hours. he then asked for my banking details I said no i will call the bank back myself. He started to get agitated so i hung up and called my bank. My bank confirmed it was a scam caller and I was very lucky that i didnt give them any details.
