You opened a return case of course!!!!
Doing returns properly if NOT AS DESCRIBED and you get a reply Paid Label and on return to seller you get a refund, if not you escalate to ebay.
Seller has taken advantage of you and I suspect you don't even have tracking. If you do have tracking proving delivery, you can still open a Not As Described Case to get a Refund, but you won't get a refund of the return postage.
If only you had read the information on every listing top right , MONEY BACK GUARANTEE
