I have ordered dell studio 1558 6 cell battery on jul 14, 2016 1:03:39 pm and order number is[protected]. I received the order and it was not working.
I mail back to cumpuindia and informed that product is not working. They asked me to contact technical support team. I have contacted and they replied this battery is not under warranty and can not be replaced. I tried calling cumpuindia customer care, not connecting

Why did cumpuindia delivered me old battery, which is not under warranty?
I have attached the invoice number
