They said it was Telstra Calling and they were going to disconnect my internet, because someone else was using it. This was the number he gave me when I asked to call him back to make sure he was calling from Telstra. It does not exist. He then asked me to call and ask for David , but he had identified himself as Jason when he started his spiel. He then had cheek to ask if my computer was on and could I turn it on now. At which point I said “Ah! Here comes the scam.“ He immediately hung up.
