Refund for wordpress theme - awful theme

I would like to know how I request my money back to Envato.
I purchased a WP theme, that is AWFUL, tried the support and they only want to do customizations and do “book” answers, without a propper solution.
I will be buying a new theme for the site, and throw to the garbage 3 weeks wasted on this theme on development and staff on this. What a complete waste.
I would like a contact from Envato to solve this, and to get a refund or a discount code for the purchase of the new theme.
