There is strict no refund policy for Premium Subscription no matter if it is a Monthly, Yearly or one-time subscription.
However, Refunds will be given when the code from premium content doesn’t work as mentioned in the article for that specific theme only when requested for that specific tutorial before signing up for the membership. I don’t give guarantee for free contents.
You will need to provide FTP or SFTP details with WordPress access to check it from my end, and If I am not able to make it work like shown in the demo video/image/screenshot, You will receive a full refund.
Once a refund is processed, You will not eligible for any more refund in future.
