The termination of an account doesn't have an impact on your subscription payments. For that you also need to cancel your subscription.
To delete your account (we're really sorry to see you leave), open your account management, log in and click on 'My Account'.
Scroll down to the bottom of the page and click on 'Delete Account'.
An account termination can't be made undone. It's final, meaning you can't ever recreate it again, neither by the PUK for this account nor by our support.
When deleting an account a possible existing subscription will also be terminated and any run time left will be lost. Please note that there will be no refund for any remaining days of a terminated subscription. Also not possible is a transfer of remaining run time to a different account.
