I just called them on that Aussie number, then they called me back from US phone +1-888-727-1224. I have tried calling this US number but it doesn’t seem to answer right now, but appears to have recently been used by tech support scammers according to this link replace/d/8806-first-time-putting-one-on-here .
Well since they use GoDaddy, you could possibly call them and tell someone there that a scam site has been set up and if you tell them the domain, chances are it’ll get taken down (I’ve done it before and I’ve seen someone on YouTube do it before)
