Did you submit your end read 9/8/23 ?
Did AGL get an actual read for the period too, or (I'm guessing here) was it possibly an estimated read ?
If an incorrect reading is taken in a period, either manual meter read was wrong, or an over / under estimated read was given by AGL, then the next period it will balance out when a new read is done, either by the contractor doing the manual read, or you submitting a read.
I've had situations at my workshop, where access is often restricted due to a placid dog, or locked gate, where all the tennants there have had estimated reads for 3 quarters in a row !
If it was too far out of actual reads, I would contact AGL and get an adjustment.
If your read was used on the bill, then the new period read WAS 253hwh less, then yes, it seems to be an overcharge.
Maybe they will address it if brought to their attention.
