Hi..
Order Laptop battery from Flipkart, order was fulfilled by Rga IT.

Laptop Battery stopped working after 4 got replacement as the replacement bettery stopped working in month now they it's out of warranty.

They say warranty will be applicable from date of purchase.
While replacing bettery said said over mail it new battery and warranty sticker has been put.

Now they are denied for replacement
