I Need a Refund for a Mistaken Kling AI Subscription Purchase

I am writing regarding an issue with a subscription payment I made on the 클링AI website. On May 29, 2026, I mistakenly used another person's account instead of my own and completed a subscription purchase by card payment through the 클링AI web page. The purchase/transaction number shown for this payment is 889202151443669009. Since the subscription was purchased on the wrong account by mistake and I cannot use this service as intended, I kindly request that this payment be canceled and the full amount refunded to the card used for the transaction. I would appreciate it if you could review this situation and inform me about the refund process as soon as possible.
