I’m sorry to hear of the issues with your account. I’ve just taken a look myself, and hopefully I can offer some clarity on the situation.
Your electricity meter has a Rate 1, Rate 2, and Total Rate (1+2). Bulb need your Rate 1 and Rate 2 meter readings, so that we can bill you on our day rate and our night rate. Last year however, the total rate was accidentally submitted instead of Rate 1, causing a massive jump up in your usage and a very high bill. We have a system in place to prevent things like this from happening, so we’re really sorry that we missed this one.
At the time of the high bill, you gave us a call and we managed to resolve the issue by changing your readings back. Sadly however, we missed one vital step - your estimated yearly consumption had increased to be in line with the jump up in usage, and wasn’t re-adjusted back down, as we corrected the readings.
Therefore ever since this high bill, our billing system thought that the consumption at your property was much higher than it actually was, so all of your estimated statements were based off this erroneous usage.
Every time you submitted a new meter reading, we corrected your balance - but we completely agree that you shouldn’t have to put up with crazy estimates in between submitting actual meter readings.
I’ve just manually adjusted your estimated annual consumption and re-billed you to your recent readings. This should be the end of those high bills - we’re really sorry that this didn’t happen sooner. If you ever need a hand with an issue in the future, feel free to drop me a message.
