Hi @jemijam14
Sorry you've been frustrated by these inaccurately estimated bills.
Meter readings are performed by your local distributor, not by AGL, and until we receive an updated reading from your distributor, we need to estimate your usage. Of course, when we do receive an actual reading, your bill is amended and you are credited if the estimate was too high, and charged the extra if the estimate was too low.
Fortunately, avoiding estimated bills is as easy as submitting your own meter reads. You can do this through your My Account here or through the AGL app. There are guides on how to do this here:
If you need help with performing an accurate meter read, we have a guide for that here: How to Read Your Meter
