Contacting a seller

[royalszar23]

How do I get in contact with a seller about shipping my product if eBay has removed the item in which I've already paid for and any trace of the seller from their database? The item is no longer included in myebay under the items I'm buying and even when I can find the item for a moment, I receive a statement saying I'm not purchasing the item, so there's no way for me to get in contact with the seller. I have attempted opening a case to no avail. How then am I supposed to receive the item I paid for or even get a refund back for the item I'm obviously never going to receive?
