구독 결제 환불 요청 드립니다.

Hello, ​@양다윗. Thank you for your post, and apologies for replying in English; I don’t speak Korean. 

It’s totally understandable that you’d like to get a refund for an unexpected charge, and I’m glad to hear that you have already canceled the plan even if you had some difficulty in doing so. Since we are unable to directly assist with billing and account issues here in the forum, I created a ticket for you with our customer support team. You should get an email notification of that shortly, and you’re welcome to reply to that with any additional information about the invoice and charge. Thank you for your patience, and let me know if you have any questions!
