Charged annually, then charged monthly, then charged again for sharing files with Dev. Such BS.

I paid for an annual subscription back in November ‘24, then for some reason when I shared files with my developer, (something every freelance designer has to do) I started getting monthly charges, then, So I pay for a full annual account, and now I’m being charged for 2 full seats for me and someone else that has his own figma account, just for sharing files with him. Why would I be charged for 2 seats, if my seat should’ve been covered under my annual subscription, plus a coworker? I’ve been triple charged. So unethical. Would like a refund.
