Hello BarryHamm,
Welcome to AGL Community!
When a reading is provided that shows that previous bills readings were too low, the system just sets up for an adjustment on the next invoice to avoid increasing the bill, however given that you also have solar this would affect the price of the bill so I do understand you wanting a new invoice.
As you have already attempted to resolved this with our customer care team unsuccessfully, please send me a private message with your account information and I will help you get this resolved.
Thanks
Ellen
