Hey Loundja, Celine from the Community Support team at Figma here. Thanks for reaching out in the Figma Forum, and for the clear details. Since you subscribed and realized right after that your company already provides you with Figma Professional plan, I understand you'd like this personal subscription cancelled and the charge refunded.
Regarding refunds, payments are generally non-refundable under Figma's Terms of Service, but our support team can take a closer look at your specific case.
I've gone ahead and created a support ticket on your behalf so our support team can review your account and process this.
Since this involves account-specific billing details, they'll take it from there and follow up with you directly through your case. For reference, your case number is 2144529, sent to your email address: bxxxxi@gxxxl.xxm. Please check directly your inbox, and share any additional information directly there. Thanks for letting us know right away!
Update: The support team has replied to you, your plan has been cancelled as requested. Please check your inbox for the full details, thank you!
