Caller: Caller advised they were from NBN working with my internet provider.

This was clearly, without a doubt a scam call. Firstly, I don't have NBN so that was a big give away and secondly the male Indian caller advised me their name was John Wilson. Sadly for them I was not dumb enough to fall for the "someone has been using your internet and doing illegal/scam activities" trick. It was entertaining though, playing along with what they asked me to do when really I'm sitting on my phone watching tik toks.
