If you paid trough PP and used eBay you are covered, just open up a case then when the member doesn't respond or even if they do you can escalate it to a claim if you can not come to an agreement, add photos of box and its contents and you will win your case its just that easy.
I have had to do this at least 20-30 times, I have 537 eBay transactions it never ceases to amaze me reference how may scumbags troll eBay in an effort to scam people.
Same goes when shipping and selling on eBay it works on the other end too. I had a guy say he did not get a Canon 70-200 F4 IS lens. I had shipped it FedEx ground, Direct signature requirement, and the amount disclosed. As usual I take photos of all by boxes once they are in FedEx hands with the label showing once it's in the hands of FedEx. The buyer said I shipped him car pats (yea scumbag) and that he never got the lens. I almost lost this one but flied a claim with FedEx and it was replaced without incident.
Guess anyone can get screwed if you don't dot your i's and cross your t's one mistake can cost you on eBay its seriously lopsided for the buyer don't know why.
Hope it all works out at least it's not a huge amount.
