Service is poor i@ NOKIA CARE( SAMURADHI TECHNOLOGIES) They just do a walkaround to your phone charging RS 50,and then replace the part with new component (cost burden) rather than repairing. In my case, they told my Lumia 720 is unrepairable and suggested to exchange for Rs1000 with new mobile(who are they).Plus a bonus of sim /memory card tray missing when I got phone from them after 30 mins.Since it was told unrepairable i didn't pay attention much to it.Now it costs Rs650+ to me each.
Stay alert with them and check your phone parts before leaving.
