I didn't answer but am also getting calls from 0476 154 803 over and over saying they are Amazon... I don't use Amazon. They are also leaving messages with an Aussie accent!

Caller: (07) 3073 1449

Them : Hi I am calling from Telstra, you have a virus in your Wifi. Please tell me the number of devices linked to the Wifi.
Me : If you are from Telstra, you should have that visibility. Could you please provide me more information about Telstra?
Them : You want more information about me or Telstra?
Me : Telstra
Them : I thought you'll be more interested in me.

I hung up.

Missed call & after reading all this, Aint calling back.

I have had many calls this week from Teslstra Broadband and I immediately ask them for my IP address and they hang up.

three calls from QLD supposedly within an hour of each other
