Na they aren't doing that ( yet ). They just keep coming up with different reasons to say i owe them $300 a month. None of which are related to how much i actually use. On my bill it boldly says i only use something like $30 a month worth of power. But for some unexplained reason they're finding another $270 to throw onto it. ( literally no explanation for it, it just shows up at the bottom of my bill and every time i call them they don't exactly know why it's there but they can't take it off )
Though it is quite odd that you're bill is only $30 a month. Maybe they swapped the numbers round? Doubtful but anything is possible. Cutting usage should get to the bottom of it though.
On a different note I wish my badges would get sorted out though. Should be 1 FaT, 1 CC and 1 Millionaire badge.
