Ebay.in — Samsung evo 32gb micro sd sdhc class 10 memory card with warranty

I have purchased a samsung evo 32 gb micro sd sdhc class 10 memory card with warranty" (item id:[protected] paisapay id : [protected]. on 24-apr-16 and same was received to me on 27th april.
I was out of town for few days and didn't get any chance to check the item. on 3rd june 2016 when i tried to use that card, it is shown a read only card and has one folder pre-written on it. i have tried every way to format and make it readable but i am unable to do so. the contact details of dealer are name: naresh chand email: [protected]@gmail.com phone:[protected]
But the number is switched off all the time. ebay says they can not help as 30 days have been passed. but the card in under warranty so the dealer should replace the card and its ebays responsibility to see that dealer is providing original products.
Ebay should either replace the card or refund the money. my ebay id is svad5165
