Optus is making me mad.
First, my wife's phone gets those b-s texts telling her she's paying for some gaming crap (from a company that Optus is in cahoots with). This is some company that purports to be a 'game' site or something. Problem is, you're paying for nothing. Whatever their 'product' is, you have no way of accessing it.
Damn you Optus. I can't even see the breakdown of my latest bill that appears to have over $25 charges from this b-s company.
Another email to the TIO I guess.
Pretty weird all your options are greyed out. Have you tried a different browser? I just tested it on my own account and it's fine for me. Anyway, first thing TIO will ask is have you tried to contact Optus and posting on here doesn't really count. I'd jump onto Live Chat and request to be opted out - http://yesopt.us/chat2us
As for the charges, yes these sites are really hammering people at the moment. Same deal, on live chat you can request that these charges are disputed. They'll lodge the request and you should be contacted within 2 business days to resolve. Whilst on Live Chat, you should also request your premium SMS spend limit is reduced to $0 (default is $200) so this can't happen again.
It's already legal for Telstra and Optus to forward your phone number to scam artists. The default position is that everything is legal, until some politicians make a law against it. Obama passed a law against ISPs selling your browsing history, but Trump killed the law.
