Persistently phoned re computer security

Phones each day but never leaves a message.

Has called most days in last week, often more than once, but leaves no message.

This same person had called me saying that there is a problem with my computer. I told him I don't have a computer but then he asked me about the WiFi. I told him that it's none of his business and I'll call Telstra and he hung up.

Phones regularly during the day, never leaves a message.

Keep calling. I never picked up though.

Indian scammers, wanting access to your computer, after saying that they are from IT support and that they received an "error" message from your computer, that others are using your IP address and that your computer is being hacked. If you say that you don't have a computer, they hang up.

As per previous. Lady by the name of Sharon has phoned twice asking if I have a laptop or Ipad. Unable to call the number back so I would suggest that it is an outgoing only PBX line.
