Refund request for monthly seat on Figma team account

Hey ​@이유진, thanks for reaching out! I'll be replying in English but please let me know if something is unclear, happy to clarify.

Looking at the invoice you shared, your Monthly costs section already shows 5 Full seats and 1 Dev seat, which matches what you want to end up with. So the seat correction you made looks like it's taken effect there. The part still in question is the separate Billing adjustments line ($146.30), which is what tends to show up when a seat type changes more than once within the same billing period.

A couple of things worth checking on your end:

1. Head to Admin > People and confirm all five members are showing as Full seats under the Seat type column, just to be sure the correction is fully reflected.
2. Click the Learn more link next to Billing adjustments on your invoice. It breaks down which specific changes make up that $146.30.

I can't look into your account specifics here on the forum for security reasons, but our customer support team can take a closer look at the invoice and the seat changes behind it. Could you please submit a request through our Support hub? They’ll be able to review this in detail and help out.

Hope this helps and let me know if anything else comes up!
