Your bundle included a domain registration.
If you'd like, I can cancel and refund the rest of the bundle for $73.
As for the domain, if we cancel the domain, the cancellation process can take several weeks, and even then you may not be able to re-register the domain later.
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.
Of course, I can give you the full $99 refund too if you don't mind the chance of losing opengateproject.org.
Please let us know how you'd like to proceed!
