Nokia - Absurd charges for handset repair

I have been using a Nokia N97 mobile handset for 2 years. It has two very minor problems: broken plastic keyguard and loose steel frame. Everything else i.e. all hardware and software is working perfectly. I took it to Nokia Customaer Care Kolkata (Gariahat Branch) for repair. They gave me estimates of Rs. 2200, Rs.2800 and Rs. 3400 respectively during the last 30 days with an increment of Rs. 600 every 15 days. I found it absurd and ridiculous and talked with the manager of the Nokia Care Centre (one Mr. Abhijit Chatterjee) who explained that cost of parts are increasing continously. He also refused to submit these estimates in writing unless i deposited the handset for repair at the final rate (Rs.3400). That would mean i am agreeing to have it repaired for the said sum which i naturally refuse to do. I think the whole thing is preposturous and the customer is being taken for a ride.

Regards.
