Hi @Blake911 ,
Unexpectedly high bills can happen for lots of reasons - a mistaken meter reading is one of them. If a mistake was made, don't worry, it's easily fixed.
A good place to start looking into a high bill is our Unexpected High Bill page, but if you'd like us to investigate, just log in to your My Account page and hit the Message (💬) button in the bottom right, or the top left on the AGL app.
