Replacement of themes

Hello Good day.
I purchased a React JS Flone theme instead of Flone HTML please is there a way this theme can be replaced or something. I have no idea of how to customize the React JS themes.
The React JS theme costs 4 more, I don't mind forfeiting the 4

if you didn’t download yet then you can get a refund. If already downloaded and both item come from the same auhtor then you can contact author and let them know they will assist you.

How to contact an author to get support or for any technical query:


I tried using the how to contact author link, it displays the error in the screenshot.
I already downloaded the theme

just checked the link above and working fine. Please check again, if need clear browser cache.
