Apple India — Manufacturing defect in iphone 6

Address: Surat, Gujarat

I have purchased apple iPhone 6 from local retailer. The phone has fallen from pocket height which caused a hair crack in the screen resulting in a black spot on top of the left hand side on the screen. This is purely a manufacturing fault as apple has made iphone 6 so fregile that it cant even sustain a single drop from pant pocket height." Ivenus" is a premium reseller and authorised service provider for Apple products. As i went there to show phone's deficiency they simply deny to accept and leave me frustrated saying screen replacement would cost 22, 500 indian rupees. Kindly help in attaining the above mentioned problem.
