[Resolved]  Nokia 5310 — Unethical behavior of Nokia care center (Instant Solutions, Gurgaon)

I have been repaired my mobile from your nokia care center (Instant Solutions, Gurgaon). My mobile was in the guarantee period but they have charged INR 1, 550 vide TCR number 10051 dated 6th August 2009 for display change. Before repairing all the functions of my mobile are perfectly working except display and this has been quoted on the Job sheet of Nokia care center. Upon repairing I noticed the navigation button and side button using for music are not working. The next day I have complained it to the executive of that center and after my complain they are saying it might happened that these functions were not working before repair. Now they need 10 days to verify and shorted out for this problem and asking for further payment for repairing and testing charges. Please verify the case and give me a solution. Also ensure that such problems do not creep up in future and that our faith in Nokia remains undaunted.
