The c(Rocky agenciesc) Nokia authorized center opposite to Satyam theatre is at a fraud. I don't know why Nokia firm itself giving rights to such a service centres.
The service centre Managerc ( MR.pondiyarajan ) is the head for these fraud activities. They will simply steal ur mobile phone parts or sometimes the phone itself. Mostly They will remove the new mobile phone's display / circuit boards during there service. Please carefUl.

Thank you
