Returned Trainers never arrived

[nickers0_000]

Hi, so I sold a pair of Yeezy trainers. Anyway the buyer apparently bought them by accident so asked for a return. 
before I had chance to do anything EBay accepted and refunded the buyer before the trainers were sent back. I've been on eBay 17 years and have 860 odd positive feedback so would have had no problem dealing with Thisbe I have done many times.  
Anyway eBay has somehow lost my trainers at their new authentication centre. This hasn't stoped them keeping all the money for the next item I sold and are now chasing me mercilessly for the balance of the refund, of course they have not deducted the commission they made on the original sell of the Yeezys. I have been slowly removing all my listings from eBay as I personally think they have recently massively gone down hill. 
They also deduct on average 15% from my sells but when I spoke to an advisor he insisted that commission is always less than 10%. I can't get any sense out of them when I call! What can I do? Thanks

eBay authenticity for sellers is Here

and for buyers Here

Useful links and eBay bay inform us that “Browse and shop eBay’s listings with the “Authenticity Guarantee” badge.” And “eBay has partnered with Sneaker Con” Looking at the listing in question here I cannot see the 'badge' but see the seller has put on the listing that they are - “OFFICIAL EBAY AUTHENTICATOR” And, “I AM AN OFFICIAL EBAY SNEAKER AUTHENTICATOR WHICH MEANS YOUR TRAINERS ARE GUARANTEED TO BE AUTHENTIC” What am I missing? 61stephenuk arkwebus

Please tell us more about the "EBay new authentication centre"  I have never heard of it.  I do not know everything of course but cannot find anything simply on help and contact.  EBay.com seems to have such a scheme [USA?] but one of the problems for sellers is that eBay never sees the items sold.  They use the term "sneakers" which is not in general use in UK I think.

If a buyer opens a case the seller does have to respond to it quickly.  If not ebay may simply close the case and refund without return.

So Ebay now check sneakers that are often counterfeited on their way to the buyer. They also check them again on the way back if they are returned to make sure you are getting the same ones back that you sent out. This is where it seems my trainers have been lost. When I track them on the return is says they have been delivered but to the authentification

Basically EBay have misplaced my trainers on their way back to me but are still chasing me for the refund money. I say until I get the trainers back which they have had I owe them nothing and they actually owe me the money for the item they kept the money for that I sold after.

Looking at the listing item 274816720962 I cannot see the 'badge' but see that you have stated on the listing

“I AM AN OFFICIAL EBAY SNEAKER AUTHENTICATOR WHICH MEANS YOUR TRAINERS ARE GUARANTEED TO BE AUTHENTIC”
