Amazon fees when open a new seller account

Hello everyone,

I just opened a new seller account on Amazon France, and it charged me 46.80€. When setting up the account, it automatically selected the Pro option, but I downgraded to the Individual option right after opening the account. Is this fee an opening fee for the new store, or is it the first month’s fee for the Pro account? Since I downgraded to the lower plan, will they refund this amount later?

Thank you.
