Nokia Mobile Phone — poor service

I have purschased a new model multimedia nokia phone model no 5220 express music from an authorised sales centre, nokia priority, chinnakada, kollam, kerala, india just a month before, but on 1/10/2008 the speaker of the phone went out while i was listening music, because the company has provided a 6 month warranty for the handset I gave the set to the authorised service centre of nokia, kollam, kerala on 3/10/2008 because of public holiday on 2nd. they gave me a job sheet saying that the speaker has been damaged and for changing it should be sent to kochi, kerala and will get the set in 7 days .After 7 days excuelding the national holidays I contacted them, but they said that the set is not yet been sent from kochi because of short spare, so that they will give it after 3 more days, but till today 18/10/2008 they have not return the set, now they are saying that the board is complaint and there is no spare to change so i should wait for another one more week, so conculding I am not at all satisfied with the service, How could a reputed firm like nokia wait a customer more than 3 weeks saying that there is no spare available now during the warranty period itself
