Caller: Spam

Spam. Said they are from Telstra in Melbourne and that someone has hacked my internet. Do you let me connect to your computer because if you do. They will gain access to all your files and add a virus.

Spam call tried to say they were from Telstra. Something wrong with my internet.
Very thick accented Indian lady.

I never call back unknown numbers but as I’d just arrived in Brisbane, I thought it my hotel calling me. The number was not connected so seems to be diverting to a number not registered. They tried again and did not leave a message. I’m not calling it again and most likely will block.
