After looking into your account, I found that the domain you registered is:
Do you have to completely cancel this domain? Please note that this is different from other upgrades and is stated during the purchase process.
Canceling a domain at this time means you completely give up ownership of the domain. There is no guarantee the domain will become available to re-register after cancellation.
If you would like to completely cancel your ownership of the domain name, please reply to confirm.
Feel free to reach out if you have any questions!
