I called back number 0423 653 634 ran gonce then gets disconnected automatically.

Spam call, didn't answer it, tried to call back and was unable to connect. Block

Called once, didn’t recognise the number so didn’t answer. It stopped ringing early, and never left a message.

Hi ho, hi ho, onto the blocked list you go....

called the number back and was disconnected

Probably best to block.

Caller: 0423 653 634

This number tried to phone me I couldn’t answer on the spot because I was busy they never did leave me a voicemail or sms me. I tried to return the call anyway when I could it just hung up right away.

I never pick up calls from number not known. They can leave a message if it is important
