Always, remember to buy from good Sellers (see feedback and his sales count of that item you like to buy and overall sales) even though there is a little increase in price. Inquire the Seller if he can provide better product, service if you pay more price. Talk atleast once to the Seller to understand his tone and way of speech before placing order especially when you are placing order for high worth items.
Current case,
You may need to talk to Seller once and seek his solutions first.
If he don't cooperate, have full evidence in photos and then submit to inrswebhelp@ebay.com and ask them to open SNAD case. Buyer is just equal as Seller, hope you are true as Buyer, you will get justice. But be true.
I think you can return and get refund if the deal is not impressive. Seller generally accepts. Hope you will have your day.
