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 - 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.
