Just left a voicemail saying hello - annoying.

I never answer a call that isn't in my address book... After subsequently googling the number and finding this page.... on to the call block list.. which is getting larger by the week.... @#$@#$#@ telemarketers!

Another annoying hang up. They always seem to be Optus numbers. It's usually some Asian call centre.

Trojan scam

They just hung up
Annoying

Spam call, said goodbye and hung up

Missed the call thankfully, bldy pests.

Just said goodbye

I called back number (03) 8091 4647 rang once then goes to busy tone.
