Schedule a cancellation. My Page → Class+ Subscription Management → Cancel
When you schedule a cancellation, you can continue taking classes until the end of your paid period — only the next renewal payment will not be processed. Since this is not an immediate refund, you won't lose any remaining time.
⚠️ Removing your card will not stop automatic payments. Make sure to schedule a cancellation. The card used to pay for your subscription cannot be deleted while the subscription is active. You can delete it after cancellation. If you paid for your subscription via Naver Pay, scheduling a cancellation alone will not deregister it — it will be removed after the subscription has actually ended.
To change the card used for renewal payments, add a new card and tap [Set as Default]. Starting from the next scheduled renewal date, that card will be charged, and your existing installment plan will remain the same.
