Something must be seriously wrong, I'd be ringing them too! Our last bill was about $1200, but lately they've always been around the $1000 mark anyway (and I still have a mini heart attack everytime we get the bill!). If you do end up having to pay it, make sure they give ample time to pay it off...Country Energy direct debit about $50/fortnight from our bank account and I make additional payments on top of that, otherwise we would never pay it off, but it's still usually only just paid (or we have a few weeks) before the next reading is due. They haven't disconnected us yet
