rang at 11.20pm Tues 31 May but did not leave message. Looks like a scam call

Called pretending to be CommBank Australia, warning me of suspicious account activity that was not even present on my account. SCAM! Beware

Ringing saying to update nbn to fibre then when I told them I am already connect, they said would look s server. I told them no as I am connected, then they hung up.

Recorded message - said from Amazon that someone hacked into my account. I hung up

Rings and hangs up if you happen to answer

Scammer style call, hung up on outgoing message, could be wrong though!
