Hey @차승현, thanks for reaching out! I’m replying in English, so please let me know if anything is unclear and I’m happy to clarify.
For privacy and security reasons, we can’t look into billing details here on the forum. Please submit a request through our Support Hub. Our Customer Support team can securely review your account and the charge, and pick it up from there.
In the meantime, you can check your plan summary, seats, and invoice history in the Billing tab of your admin settings. This article walks through it: Manage billing on the Professional plan.
Hope this helps!
