I want the money that the plugin cost me back

Hello, I am not satisfied with the result of the plugin as it does not work on my wordpres 4.7 theme. I would like the refund of the amount that the plugin cost me. How do you do this?
I’ve been trying all day to contact the technical support of the same and I have not received a response.

You need to request help from the plugins author, or you can check the following links:

For author: https://codecanyon.net/page/author_refund_policy
Hope this helped you.
