Consumer Redressal

I have brought a Blackberry curve 9320 mobile handset @ Reliance digital B\'lore on 24/09/2012 and still my handset is in warranty period some of the keys of keypad , symbol uppercase and numeric keys are not working when i reported this problem to the Authorised service center they informed me that it wont be covered under warranty since i need to get it repaired on my own expences inspite of company warranty period.so i do request you to consider my complaints and provide me an proper redressal for my cause.
