You can cancel your Premium Theme and get a full refund within 30 days of purchase.
Please go to the Store section of your dashboard, where you'll find the theme in the list of your upgrades, along with a "Cancel" button.
If we cancel the domain, it can take up to several weeks, and we can't guarantee that your domain will be available to you again once canceled.
If you want to keep using your domain but you don't want to use WordPress.com anymore, you don't have to cancel it.
Instead, you can move the domain to another site, using the Domain Administration tool under Store > Domains, at the bottom of the page.
If you don't want this domain at all, you can cancel it for a full refund if you purchased it within the last two days.
To cancel the domain, go to Store > Domains in your dashboard. Locate the domain you want to cancel in the list, and click on the Cancel button next to it.
This cannot be undone, so please follow the on-screen instructions carefully before you confirm the cancellation.
