Sorry to hear that you are so disappointed with the plugin.
Please note that the plugin offers a contact form connected to PayPal as described in this WordPress directory. It includes all the features mentioned in the description and those features are fully functional. In most cases a the classic contact form is all what is needed and there are many users using it.
The optional form builder (pro version) isn't mentioned or offered in the plugin description in this WordPress directory.
Thank you for your feedback.
