Refund wrongly issued

Hi, I recently sold an item and the package went to a wrong address. The buyer raised an issue so I sent her a new one and I have had good communication with her. The new item is on its way and I have tracking to show its nearly there. Now eBay have decided to refund the customer even though it’s on its way and I provided all this information to Ebay and to the buyer. I cannot seem to get help from them so how to I appeal this as I’m just going around in circles!!

im almost in tears as the other box has been received by someone else so now I’m well out of pocket
