To add to Eric's post, it does look like this slipped through the cracks, perhaps because some other members of the community were assisting you. Regardless, our Support Engineer can work directly with you through the open ticket, which you can access from your Support History page on our website. supporthistory.php
Our Extension library page does state that there are no refunds for enrollment fees. It is on the Frequently Asked Question section of the page.
Our apologies and we hope we can work with you to resolve your issues using Form Builder.
