I couldn’t figure out how to install the theme. I decided that I did not need it after trying to contact support and not receiving any response. I have been denied a refund. Has anyone else been able to get a refund or does this company just take your money and not allow you to be refunded?
If the item is genuinely broken or not functioning correctly then you would get a refund.
Typically not being able to install the item (depending on why this is the case) would not necessarily justify a refund as per guidelines https://themeforest.net/page/customer_refund_policy
Did you ask the author for a refund or envato?
