Hey @Francesca albergo, welcome to Figma Forum.
Thanks for flagging this. I can’t access billing settings from this public thread, but Customer Support can look into the charge and the reminder emails. I’ve opened case: 2190366, and emailed you with what they’ll need.
In case this may explain what you’re seeing, a canceled Professional plan stays active through the end of the billing period, and seats added during that period are prorated onto the final invoice. More details here: Upgrade or downgrade your plan → Downgrade or cancel your plan.
Appreciate your patience as we follow up on this. 🙏🏻
