[Resolved]  Ebay.in — received a duplicate product without invoice

Website:

ebay.in

Hi,
I have bought a battery for my samsung galaxy a7 from ebay.in on 14/12/2017.
I received it on 18/12/2017 with no invoice.
I went to a mobile repair shop on 25/12/2017 to get the battery replaced because the phone comes with an in-built battery and only a technician can replace it. While replacing the technician found out that the battery is slightly swollen and was not getting assembled in my phone. I immediately raised a claim to return the battery on ebay.in and sent the images of the battery to the seller as well as to the ebay claim department. 2 days later i received a message from ebay saying that the claim is not eligible and has been rejected. I called ebay india again and re-raised the claim to return the product. Then again i received a rejection message from ebay saying this-
"regarding ebay guarantee claim 3355418. We are sorry to inform that your claim is not eligible as the product is under manufacturer warranty. Please visit the nearest authorized service center to resolve the issue. Visit your 'my ebay messages' http://goo.gl/2KpeXb section for more details."
Then i received a call from them and they said that we are arranging to provide you manufacturer warranty card and you will have to visit the samsung service centre to get it replaced to which i told them that why should i visit to the service centre for a fault which you have done by sending me a duplicate, fake and swollen battery but they denied it all and kept iterating that we are arranging to provide you a manufacturers warranty card and we are not going to return it at all.
Please help me from getting cheated by ebay, they have sent me a duplicate and swollen battery and are not in a mood to return it.
Also when i received the battery, the outer courier polythene bag was sealed but inside the bag the battery was in a losse packet and there was no invoice of the product. I am attaching the images of the courier packet and the battery as well.
