Is it possible to ask for a refund the money?

I had the error of buying a script that the author does not support
Does not answer the comments of the item.

And the script, besides passing the installation successfully and the server meets the requirements, does not work has many errors.

I am disappointed with my purchase. What I can do?

You can request a refund here :

Thank you.

I’m new to envato, I did not know what to do.
