Nike India — torn shoes

Address:

Moradabad, Uttar Pradesh, 244001

I recently bought a pair of shoes from nike retailer outlet, i was surprised to that the shoe started to tear within a one week interval, and when i went to the retailer for an exchange the service was just not there, instead the seller had a bad tone talking to me. Even the online customer services site does not fuction well. The shoe was labelled to be used for training purposes, i used it for running on treadmill and sprinting on grass. The shoe seems to be worn off.
I have been a regular nike customer and have purchased lots of shoes and apparels and was satisfied with the quality but this product and the way the seller reacted is very unlike the brand i used to buy and preach. Please help me avail the provided warranty and do train the sellers to be a bit more professional so as to fit into nike standards. I have safely kept the bill, expecting quick and professional customer support
