[Resolved]  Sony Ericsson G502 — Poor Quality Keypad

I bought a Sony Ericsson G502 mobile 2 months back only. The silver coating around the phone and on the keys are coming out and it seems to be a nickel coating(info. from my friend). When I asked about this n a service center they just replied that they wont take this as a issue and if I want to complain I have to bring at least 4 to 5 person with the same problem and sign the complaint letter. This is so stupid that they wont show interest on a single customer's complaints! I need to solve this immediately because I do not want the rest of the coating to fall off like a distemper on a wall.
