If you think that you will no longer use CS, you can apply for a permanent deletion of the CS account.

Please note the following before deleting an account:

1. You will not be able to reactivate the account or restore the data in your CS account after you delete it. Your purchased items (such as fax credits, C-Points, etc.) can't be restored either.

2. Deleting the account won't stop the premium subscription. If you have subscribed to the premium service, please cancel the service in your Apple or Google account first.
