The deletion of an account doesn't have an impact on your subscription payments. For that, you also need to cancel your subscription or request a refund as well.
To delete your account (we're really sorry to see you leave), open your CyberGhost account,
1. Sign in and click the "Account setting" icon.
2. It will give a drop down options and click "Account settings"
3. Scroll down to the bottom of the page and click on 'Delete Account'.
An account deletion can't be undone. It's final, meaning you can't ever recreate it again.
Please note, that cancellation doesn't result in any refunds as it is a separate event that is only triggered by the Support Department based on your request (via e-mail at firstname.lastname@example.org or via Live! Chat sessions).
