Amazed you found an email for eBay.
But what you should have done, and can still do, is send an Item Not Received claim here:
http://resolutioncentre.ebay.ca/
If the seller cannot show that the item has been delivered to you, you will be refunded by eBay or Paypal and they will go after the seller for their money.
But act promptly. There is a 45 day deadline on making these claims. And that is to the minute.
