Good for you for pointing it out, Champion. Looks like they are at least attempting to fix. That's nice.
I guess I didn't understand that you were using a mobile hotspot. That makes more sense to me as far as being charged and capped for everything. We have a few services similar to that in the states. I have two separate providers though. Mobile account for my phone when away from the home, and then traditional (uncapped) cable connections at home and work. That's were I play via WiFi "for free" so to speak, sense those are a cable internet, and unlimited access (at least my account is)
