You could have asked your question(s) and share your concerns before purchasing the item. Obviously, you had your chance to make sure that the item meets your needs.
As stated before we do have a clear refund policy and you may need to read this before submitting your request or purchasing a product in first place.
As a reminder note that the item you have purchased is a plugin, not a child theme or theme!
We do have a clear documentation for installation, setup, and configuration which helps you to save time and get to the point quickly.
We rarely provide support on this forum; you need to reach out to our dedicated support forum and start your own discussion.
Regarding the review, while we appreciate your feedback since it helps us to improve our product, this is a review section for Hypermarket theme, so reviewing Hypermarket Plus plugin here is not something allowed by the www.ads-software.com team or helpful to people interested in reviews of Hypermarket theme.
Considering this, we would appreciate if you could leave a review for Hypermarket theme (if you think it is a 1-star theme, no problem).
Best,
