Welp.
I hope this gets to you before your post is removed.
We cannot name and shame other members on the Boards.
There is a Money Back Guarantee.
Go to the bottom of this page (or most pages) and open an Item Not As Described dispute in the Resolution Centre.
The seller will be told to send you return shipping.
When tracking shows the item is returned, you will be refunded.
If the seller does not send return shipping (which can be difficult internationally) eBay will provide it, and charge the seller for it.
When tracking shows the item is returned, you will be refunded.
If the seller refuses to provide return shipping or to refund, he loses the Dispute, you will be refunded by eBay which then charges him for their money, he gets a Defect on his account and loses his selling fees. You can leave feedback.
The most effective feedback is calm and factual.
There is a process and no need to make up your own.
