I hope it’s okay to reply in English. I understand that your paid plan was unexpectedly renewed, and you are requesting a refund for the past two months.
I've checked our system, and it appears you have already canceled your plan recently (during the current billing period).
You will continue to have access to all Professional plan features until the end of your current billing period, at which point your team will be downgraded to the free Starter plan.
For your reference, you can find more details in this guide:
To protect your privacy and security, we cannot handle individual billing requests here in the public forum. That said, I will go ahead and open a support ticket on your behalf so you can discuss your situation directly with our team. You will receive a ticket confirmation email at the address associated with your Figma account shortly. Please continue the conversation there to appeal your request directly.
