Caller with strong accent claimed to be from Telstra, said my computer had been hacked, was being used by hackers, etc.

This number has rung a number of times today and doesn't leave a message. When I ring it, I get a message saying that the number I dialled was invalid or incomplete. Yet it rang me. Any ideas?

Pretending to be Telstra ringing to fix your internet. They pretend to have your secure Telstra password. Scam.

Continually getting calls, but they won't leave a message

this is happening to us too no idea whats going on

Received several calls today. One time they said it Telstra and something to do with my computer so I hung up straight away - suspected hoax/spam call.

This is a scam number and when you redial it is not correct
