Un used license Refunds

I have a few themes that I never used and won’t use as I can only work on WordPress. How can I claim refunds for these themes as I believe those licenses are meant to be monitored, and if one isn’t used I believe one can claim a refund

Not like that. If you already downloaded the theme/Item then the you are not eligible to get a refund according to the Envato refund policy. Can I Get A Refund is an explanation of the refund policy.
