Hi yngwie01,
Thank you for reaching out.
We can appreciate it's frustrating to not have an accurate estimate, however we cannot change the estimate unless some updated information is provided to us to verify how much is being used at the property.
If you have a basic meter you have the option to enter your own read at any point during the billing cycle, to update your cost so far and bill projection to be as accurate as possible.
Kind regards,
Megan
