Have you got a link to that particular preorder? Does it require upfront payment?
I'm curious because eBay's preorder policy states
And if you don't get the item
Pre-sale listings are those that describe items for sale that are not in the possession of the seller at the time of the listing.
eBay permits pre-sale listings only on a limited basis
The seller must ensure that the item will be posted within 20 days from receiving payment
The seller must clearly indicate within the listing that it's a pre-sale item with postage no later than 20 days after payment, including the date on which the item will be available to post.
Considering that this item is listed for a 2015 release, the numbers don't add up for me.You can open a case in the Resolution Centre 10-45 days after the sale (for payment outside of PayPal)
The seller has up to 10 days to respond to your case.
If you haven't closed it within 90 days after the end of the transaction, your case closes automatically.
