To cancel a license purchased through the cPanel Store:
1) Log in to the cPanel store (https://go.cpanel.net/store) account and use the following steps:
2) Go to My Account-->Manage Licenses (which is located just beneath the cPanel logo)
3) On the far right of the line which includes the IP of the license you wish to cancel, click the drop-down menu
4) Click "Cancel License"
5) As the license has been pre-paid until the end of the month, this will queue the license to cancel at the end of the month.
Please note that once the license has been canceled, the IP will be suspended from monthly billing for a period of 30 days.
