What happens if I delete a client group inside their commitment period?

When deleting a client group, which is still within the commitment period, all underlying data will be permanently deleted immediately. However, the client group record itself will remain and cannot be deleted until the end of the commitment period. 

At the time of deleting the client group, Auto-Renew will also be disabled, so the subscription ends along with the commitment period. 

For more details on client group subscriptions and commitment periods, please refer to this guide.
