Nokia Service Center — Irresponsible Nokia Service Center

I got Nokia 5130 Express Music in Feb 2009. During May a little water went into the handset. I could not switch on the mobile. SO I went to Nokia service center in VenkatNarayana road in T.Nagar,Chennai. I never knew it was recently opened center. They said the problem could e resolved within a week. When I called them back they said they want one more week. Later one day they called and said motherboard is damaged and the mobile cant be used anymore. I believed their statement and got my mobile back. But I did not want to completely believe them. SO I went to another Nokia service center in Ashok Nagar which is near hot chips. The first question they asked was whether I gave service to local service center.
I asked why. They said the person who service dnt know to handle the motherboard. There were many scratches and he showed me. Also the side bar has been damaged and quick fix has been applied to hide the damage. I think I can do better service. I mistakenly told the new service person that I serviced only in Nokia before coming to this center. And I asked him to write the complaints . He stubbornly refused and said it is against violations. Then I went back and fighted with the first Nokia center which is in T.Nagar. They said they cant do anything. There is no responsible person to speak . Then I called the Nokia customer care. They asked about my complaint and they said they cant do anything since their office is in Delhi. They asked me to talk to the manager of the center. When I asked for the manager of the center they said the person who serviced my mobile was the manager.
Hopeless managers !!!!!!!! I lost my 8000 Rs mobile
