Nokia 7610 Supernova — mishandling of handset while repairing (job sheet no.3544)

Address:

East Delhi, Delhi

I had given my handset 7610 supernova for repairing the problem of bluetooth &radio at maa communications east delhi on 7-August-2010.
After two weeks on 20-August-2010 when i recived it had scratches on screen (which were not there before)after complaining they replaced the screen.
On 21-August-2010(saturday)evening i collected my handset from the center after paying repairing charges of Rs.550.when i came back home the same problem as on 7-August was there plus it was also not charging.
I went back to them on 23-august-2010 (monday)with the complain they made it bounce but still kept it for repairing.
On 28-august-2010 they said it is not repairable and they didnt even know the problem.
After making so many calls to there center and also to nokia customer care i had not recived any satisfactory action My JOB SHEET NO-3544.
I claim my repairing charges and my handset in the same condition as it was on 7-August-2010.I also doubt mishandling of my instrument by the center.
