i Purchased samsung core2 mobile on on 6th Aug2014 but from next day it started restarting. i informed it to samsung service centre kendrapada but they advised me to wait and check for few more days , but the mobile restarting problem persisted and when i finally requested them to replace that mobile they informed me that the guarantee period has been expired and it can only be repaired. I handed over that mobile to samsung service center on 20th August but till 26th August i have not received my mobile.
