Caller: "Telstra"

They called me and told me I had internet problems even though we don't have telstra and when I told her I don't have any of the control over these things, tried to make me open a device to "fix" the problem anyway. She said my internet connection could be disconnected at any time. Definitely think it was spam cause I literally don't own an internet connection, this is my parents' house. I could hear other people in the background and I think it was a call center.
