Canceling Domains in CAP
From Lunarpages Web Hosting Wiki
If for any reason you do not wish to have a specific domain renewed you now have the ability to cancel the auto renewal process through your Customer Account Page (CAP). To cancel the renewal of your domain you can go to http://account.lunarpages.com and enter your username and password.
Once logged in, click on the link for Manage/Register Domains, locate the domain, and then click the pencil icon on the right to edit the domain information.
Scroll down a bit and you will see: This domain is set to renew. Click here to cancel.
Click the word 'here' and the bill for that domain name will be canceled.
If you want to have a domain reactivated you will need to contact us by phone or send an e-mail to email@example.com.
