Hi there @dylanjung333, welcome to Figma Forum!
I don’t speak Korean, so I hope it’s okay that I’m replying in English.
I checked this out for you, and your request is in the Customer Support queue under case: 2250186, along with the details you’ve already shared. Please look for the team’s reply by email. If you have anything to add, you can reply to that same email thread so everything stays together.
For general information on plan changes, cancellation, and Figma’s refund policy, see this guide: Upgrade or downgrade your plan.
Appreciate your patience as we follow up on this.
