Hi @sora lee, Celyn from the Figma Community Support team here. I hope it’s alright for me to reply in English.
Thanks for reaching out. I understand that you were planning to pay monthly but were enrolled in annual billing instead.
As we’re unable to review billing-related issues here in the forum, I’ve created a support ticket so our Billing team can take a closer look and assist you directly. Your ticket number is #2129613.
Someone from the team will reach out soon, so please keep an eye on your inbox. Thanks for your patience in the meantime.
