The only issue I have now is that since two people have told me that the Internet browsing isn't included I'm not so inclined to believe they just don't know what's going on.......
But yeah you make a good point nothanks, really gotta get on to the BB specific support types 'cause you really don't know if the others are that knowledgable.
It'll take some pretty hard evidence for me to believe I was just getting misinformed now though, especially since my bill never said "charges not included in your cap" until I raised the issue (conveniently I might add

)
anyhow- as far as this situation is going I'm currently at a level 2 complaint with the TIO, Optus has yet to reply to me AT ALL. Regardless of the outcome I don't plan on recommending Optus to anyone else ever again, and I seriously doubt I'll be staying with them a minute longer than I have to.
