eBay India — ebay promoting fraud sellers

I have ordered on ebay, a new hynix DDR-II 1 GB RAM with bill and warranty vide PaisaPay ID [protected]. The product delivered to me by the ebay seller mithilainfotech was 5-6 years old with HP logo. The logo of HP was clearly indicating this to be old and used part taken from some scrap. Unfortunately for me the product was not working also. I raised the ebay guarantee claim and surprisingly I found the reply from ebay that as the item is covered under warranty contact the service center. Those cheats even did not bother to confirm that product is dispatched with bill and product is same as ordered. I returned the product to seller in hope that he will replace the product. The seller sent me back another old and used product this time with Dell logo it was another old and used one I sent it back to seller and awaiting replacement or refund since last 02 months. The role of ebay in all this situation is of agent who claims his commission and turn his back on you. Thank you ebay I will make this fact know to every one that you people are big cheat and no one should buy anything from you and even if some one buy from ebay he will be at mercy of god.
