I bought an amaron battery for my house inverter purposes on 12 june 2016 with 36 months warranty from sethi agencies, bharatpur (Raj.)-321001.

He gave me only bill with battery number but not gave any warranty card. Now the battery stoped working before the expiry date. And he is now asking for warranty card, which he didn't give me at the time of purchase.
Please solve the issue.
