Nokia N95 — bad service...

I have nokia N95, it starts like this, i was on my way to Ahmednagar from Delhi on Goa express on 13Aug. on my way battery got discharged, on reaching to Ahmed nagar (near Pune) when i put it on charging it was not getting charged,
So i took it to Ahmed nagar Nokia care centre to fix the problem.
There they diagnosed it and said its a battery problem and your cell is ok, since i was on my vacations i was not carrying my cell bill to get it replaced.
When i came to Noida i showed it at nokia care centre (A-78, sector 2, Noida) and told them about the whole problem they simply took my battery with a photocopy of bill for replacing the battery, after two weeks when i got my battery, i put it on charging it again showed the same problem.
Then they again diagnosed it once again and said its a water logging problem and it will cost you around 1000 INR.
As i agreed they kept the cell with them, now after two weeks i:e on 18th Sep they returned me the cell and said me that its not repairable.
i asked for the solution the lady at the delivery counter "sir it will be better that you show it to some one out side they will fix it with jumper" I was shocked that if a local person can fix why cant you...
when i looked at my cell it was badly scratched on front panel, i complained about it and also asked them to switch it on to check whether it was working or not.
The man MR. Nishu he took it inside, after some time he came back and told me that we don’t have panel go get it replaced on Monday, when i asked him did you switched it on to check he said "Yes its working fine". I came back home and switched it on, i was amazed to say its display had lost its brightness all i could see a dark screen and its 5mp camera was not displaying any focused objects.

All this had put doubts on the diagnoses of your people at nokia care centre, why should I believe that it’s a water logging problem when other centre at Ahmednagar is saying that you cell is not a problem.

This is the storey from 13 th Aug 2008 till Sep 18 2008 now i want to know what action shall i take to get my cell repaired without much hassles and is less time.
