Sorry to hear this however the theme functions perfectly fine and the theme is very well documented, and we do understand that it might be confusing sometimes but you can find our themes documentation here as well as many great articles, and video tutorials that might help you on the way developing your website.
You certainly do not need to be very technical in order to edit it as well as we have a tutorial on how to combine different pages from different demos here
Also please understand that Commercial themes on Theme Forest often offer the framework of their own option, and they offer a lot of options, functionalities, and custom elements, and the learning curve can be steep sometimes, especially when you are facing some new theme for the first time.
We also do understand your thoughts and that is why we as well, besides, the tutorials, documentation and articles have an outstanding support team that are always eager to help all our customers. Our usual response time is within 24h and our support team is working really hard on answering all our customers requests.
So please we would kindly ask you to submit a request at our help center and our support team will be happy to help.
We do hope that you will reconsider your rating.
