1. Open the subscription (it must be the customer's current one) and click Cancel Subscription.
2. In Cancel Subscription Auto Renew, optionally tick upcoming days under Select days you want to cancel – those days are set to Canceled and their meals refunded.
3. Optionally enter a Refund to Digital Wallet amount to credit the customer's balance.
4. If Show Subscription Cancel Reasons is on, choose a Reason (and justification if required).
5. Click Cancel Subscription.

The subscription is flagged cancelled with today's date, auto-renewal is turned off, the customer receives the Subscription: Cancel notification, an admin notification "Subscription Cancelled" is created, and the reason is stored. Upcoming days you did not tick are still fulfilled; the customer page shows "This subscription will be cancelled on <last delivery date>" until then and "The subscription is cancelled" afterwards.
