I had been gifted a Nokia N8 phone by a friend along with a bill box ect.soon after few months i started having problems with the phone thus i approached the company registered service center ,on 26th nov when the problem became serious i submitted the handset to the service center who in turn send it to the head office thus i called their call center to know about the status and they told me that my phone will be replaced but when it reached to Goa on 03 Nov 2012 i found out that the phone was not replaced but repaired and a new imei no has been given as the mother board and other parts were changed along with my screen and touch panel,but soon after 8 days from receiving the phone I found out that the phone has been fitted with fake parts ,while i was charging my phone on 11 Nov.2012 the handset automatically got warmed up like before and the screen of the phone automatically cracked ! thus i approached the company but everything i call them they say give us 2 days time and we will call you back but they never called me back to till day! an if I call them they either hang up or put me on long hold and later say that your phone is working fine.I really dont know now what to do and whom to contact !please help ..this phone is just 9mnts old .and now is a total waste !..it was bought for rs 19500
