THIS IS A SCAM

I was looking for free sheet music for a christmas carol and clicked on a dodgy looking site, so I was already on high alert.
I'm not very computer savvy, but it looked pretty convincing. I kinda knew it was dodgy though and after a bit of looking I put the contact number into a different web browser and found this website.

tried to get me too. 1800 numbers have to be applled for by a co. with an ABN. They should be easy to stop by TIO.

They asked me for $300. Though I was a minor with a card(eftpos) they proceeded to ask be about my details. Once they found out I did not have a 3 digit number on the back of my card they hung up... I am a minor(17 years old) and have never gone through this before so I was really sceptical yet worried that my computer would be corrupted as I use it for school.
Do not trust :/

Pop up that I got from kissanime.com asking me to call this number for technical support. Just use task manager like simon says to close the browser then restart ur browser.

Scam............
Telstra or any other authority will be powerless to do anything about this because they are a dog with out a bite
