Caller: Scammer?

Said they were from Telstra and that my internet was being compromised. They confirmed it was my NBN ( which I don’t have) told me people were using my internet. When I asked where they lived he said QLD and WA. I asked their names and he said their name was Brut. He then went on to say Brut lived in America. I called him out on it and he then said people from QLD and WA were giving the information to Brut in America. He prompted me to get in front of my computer so he could help me fix it. I said I don’t have one. Lol. He then told me I was a f@!$n liar and to f@!k off.
