Hey there! Celine from the Community Support team at Figma here. Thanks for sharing the screenshots here. I don’t speak Korean so I will continue in English, hope it’s ok!
A couple of things worth clarifying: on the Professional plan, billing works at the team level, covering all paid seats together (not per individual person). So even though your own seat was changed to a free View seat on August 5, the charge on August 12 is most likely the team's regular subscription renewal, covering other paid seats still active on "cream_blue," not a charge tied to your now-unused seat.
Per our Help Center: "We won't issue a prorated refund when you downgrade a user to a free View seat, or remove the seat. However, someone else at your company can use the paid seat for the remainder of the billing period. If you no longer need the seat, make that adjustment at your next plan renewal."
So the seat itself doesn't disappear or stop being billed immediately — it stays available for someone else on the team to use until the next renewal, which is when seat counts get adjusted.
To check the exact breakdown of what this charge covers, go to Admin → Billing on the team . Here's how to view your billing and invoices. If something still doesn't add up after checking that, I'd recommend submitting a request since our Support team can review the account, payment details and refund request directly. To do that: Go to the Support Hub / Type “Report a billing issue, Contact agent” / Click Start a chat and select Enter and follow the prompts. Thank you
