Help!!! Buyer never paid so I went to cancel and relist but accidentally marked paid and Iâ€™m charged fees

The menu choice for Unmark as Paid has been discontinued.There is no menu choice to get your seller fees refunded.You will need to contact eBay to get the fees credited to your account.See message 2 within this discussion for ways to contact eBay.https://community.ebay.com/t5/Selling/Tons-of-Listings-Removed-Chance-listings-policy/m-p/33961457#M2269466
