Caller: 'Telstra' scammer

Indian sounding voices that claimed they were from telstra. Kept on telling me that Hackers were using my internet service for illegal services And I was going to be disconnected from the Internet. He gave me two IP addresses that were seemingly made up of random numbers (One was ending with a .0 ) that he claimed was hacking me. They then told me to sit in front of my computer so they could show me the problem. I asked him what operating system it should be running, He didn't know the answer In just repeated laptop or desktop. After wasting 15 minutes of their (and mine) time he told me I was being 'smart' and then said he was going to disconnect me from the Internet .
Internet still works lol
