왜 결제가 됐는지 모르겠습니다

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

Since we are unable to help with billing and account issues here in the forum, I’ve created a ticket for you with our support team regarding the charge. You should get an email shortly from me, and you’ll hear back soon from our support team. In the meantime, you are welcome to reply to the email with any additional information about your cancelation and charge. 

Have a great day!
