Nokia 2630 — Warranty Problem

I purchased the above model set from Nokia Priority dealer M/S. Pramila Agency, Jail Road, Balasore, Orissa vide their bill no. 120, dated : 19.11.2007. Now the set has no view on screen. When I send it for repairing to your service centre at station Road, balasore, they harrased me more than one month and lastly they refused to repair the above set which is under warranty period. They asked for Rs. 1200/- to repair charges. Sir tell me why will I pay ? Please take necessary action to replace the above set otherwise I will take legal action for the defect set which is lying unused and made me extra hadach for which I am loosing my business.
