This number claimed to be Telstra. Don’t believe them. Claimed I had malware on my computer. I have top of line antivirus so that is highly unlikely. When I said so he replied “Do you think you’re a technician?” At which I hung up. Was quiet but rude. Return call won’t connect.

Repeated calls from ID "unavailable". They never leave message but are persistent in ringing. I have a private landline number yet they still get thu. Annoying!

calls says nothing, i guess waiting for a response from you then a computer generated voice says "Goodbye"
