If this is how you've presented your case in the CC, I'll be surprised if even one juror voted in your favor.
A case needs to be presented along with facts, proof, pictures etc. - in this case you should have included a scanned copy of the POD showing the package weight when posted.
Btw I've sold more than a few items on eBay and I've never had a case where the buyer claimed he did not receive the item - of course I only ship via a reputed courier and with insurance. If you did not use a good courier company, it's quite possible the item was stolen.
