Consumer Redressal

I have purchased battery through SNAPDEAL with six months of manufacturer warranty on 14 April 2014. The battery was defective and for the same HP Aforesure (HP Dealer) in ahmedabad was contacted on 24 Sep 14. After all investigations, on 09th Oct 14 they generated jobsheet for replacement. Later on after one month of continuous followup HP denied to provide the replacement and stated that "Part is End of Support Life now, hence will not be able to process the case for replacement. Further to this, it also found that battery is not purchased through authorized channel, hence requesting to please contact point of purchase to get further support." Snapdeal was contacted for the same on 09th Nov 14 and even after daily follwup, till the time I am waiting for their response. Kindly help in the matter. Thanks & Regards Manish
