Theme is not compatible

I have purchased below-mentioned theme for my wordpress site. Message appearing is “Incompatible theme”. Please suggest, How to get a refund or how to use the theme

themeforest-nILc7wwi-fresh-vial-drinking-mineral-water-delivery-html-template.zip - ZIP archive, unpacked size 107,359,048 bytes

That’s a HTML template and not a WP theme. It cannot be used on WordPress.

The best option is to check and see if there is a WP version of the item, otherwise you should follow this link for more info on possible refunds. https://help.market.envato.com/hc/en-us/articles/202821460-Can-I-Get-A-Refund-
