Translate A Utility Bill's Estimated Reading Into Plain Terms

The gas bill has more than doubled and you have a suspicion it is an estimate rather than an actual reading, but the letter does not say so in plain terms anywhere. This translates the bill, tells you whether it is estimated, and gives you the exact action to take if it looks wrong. Good for anyone staring at a bill that does not add up.
