Hi there, Celine from the Community Support team at Figma here! Thanks for your patience. I was able to see your support case and added a follow-up note internally for visibility.
I can also see that our support team has now replied and confirmed that the extra seat added by mistake has been removed, so everything should be set correctly moving forward.
If you have any additional questions or concerns, please reply directly to your support case via email. That will automatically reopen the conversation with the team. (Since billing and account-related issues involve account-specific information, we're unable to review them from the Forum for privacy and security reasons.)
As your request has now been addressed by the Support team, I'll go ahead and close this topic here. Thanks!
