I have purchased the product samsung battery through paytm.
Paytm order ref: [protected]
Paytm shipment id: [protected]
The seller given with 6 months warranty. Before warranty period the battery bulged. For these i called the paytm care for warranty claim. They asked to go to samsung authorized service center for warranty claim. I gone there and they reported that the battery is not original.

So kindly do needful. Why duplicate products are sale through paytm????
