eBay

Hi I refunded 100% value in an item sold but ebay charged me final value fees. How can i have these fees refunded to me by ebay?

I sold an skateboard 07/19 and it's says is paid but i don't have it in my account in paypal neither in discover card also i was charged twice 1.40 plus 3,00 4.40 for an item i sold for less than 30 bucks? Is it correctc?
