PSE overcharging based on “Estimated” usage.

We haven’t been using our natural gas furnace much this winter since it serves the part of our house under construction. I noticed a still-high Puget Sound Energy bill and realized they’ve been “estimating” usage based on temperature and past use. I called to dispute it and they’re sending someone for a real meter read, but they said they don’t do automatic adjustments. So if they overcharge and later reads make it clear, they don’t issue refunds unless a customer requests. Kind of a crazy practice.
