Nokia C6 — asking repair charges in warranty period

Address:

Delhi

sir I procured Nokia c6-00 black mobile IMEI : [protected] from Nokia priority Partner Bhartiya Vision New Delhi on 12th April 2011 by paying Rs. 12550/-. Suddenly my display becomes blank. To rectify the problem I personally alongwith my mother visited the Nokia service & Communication Solution, A-180 (1st Floor), Sukhdev Nagar Market, Kotla Mubarak Pur New Delhi on 26th December 2011. The service centre executive has asked us to pay the Rs. 3250/- to rectify the display problem. When we told that it is under warranty then she told that the slider is physically damaged from inside therefore it is not covered under warranty.
Sir when my slider is intact then I am unable to understand that how can I damage the inside. Moreover nobody will purchase the mobile to damage it him/herself. This is the question of creditability of NOKIA not the Repair charges of Rs 3250/-. I request you that please look into the matter and instruct the service center to rectify the mistake under warranty. My other phone number is [protected] and residence Land Line is [protected]. Sir I am expecting immediate response to this email to my email id [protected]@rediffmail.com, failing to this will make me too depressed.
