Hi @shin.hyechan, Celyn from Figma Community Support here. Thanks for reaching out, and I hope it's alright for me to reply in English.
I'm sorry to hear you've been having trouble getting help. I understand that you've submitted inquiries through multiple channels regarding your billing issue and that your support requests are being closed without receiving a response.
I've taken a look at your account and can confirm that some of your support requests were merged together to help keep all communication and updates related to the same issue in one place. I apologize for any confusion caused by tickets being marked as solved or closed as part of that process.
I can see that you currently have three open tickets: #1964043, #1962201, and #1964227. I've gone ahead and flagged these with the team for visibility and follow-up.
Please keep an eye on your inbox, someone from the team will reach out to you as soon as possible. Thank you for your patience in the meantime 🙏
