Hello @Nicolas Vasquez — welcome, and sorry to hear about the trouble with your billing.
We don't currently offer support in Spanish in Figma Forum, so I hope it's okay that I'm replying in English.
I'm not able to access billing details from this public space, but I checked in with our Product Support team and they've already replied to your case. Please check your inbox for their message on ticket: 1884478, they'll have the specifics and next steps.
