We will not alter an invoice to show an amount other than the actual order value. It's our responsibility to try to rectify the situation. Please do send us a message before initiating a return. Sometimes it's more cost efficient to send the correct item out without returning the incorrect one. We want to provide the best experience possible, but we do make mistakes and are always eager to correct them in hopes of keeping your business and a reputation for awesome service behind Essenbay's name!
