Website:	samsun service centre

i have purchased a, SAMSUNG GALAXY GRAND NEO PLUS MODEL NAME :- GT-19060ZWSINS, on Apr, 2015 As i had some problem with the back key so i gave to the samsung service center situated in contrniment shopping Belgaum - 590001 karnataka on 3:10:2015 at 1:18 pm .. and todays date is 22:11:2015 and till now i did not get my mobile back from that service center . When i personally went n enquired over there the manager of that place gave a lame reason that they have give the mobile fr dharwad service center as they did not have the parts in their center. but my question is how can they give it without our permission to some other place? . but even if they have given they should return it on time right ? but nothing is possible by these people. if i call them they dont answer my call, or else they give d mobile to someother person and they will answer in such a careless manner . the manager is least bothered about my issue . my mobile is just 8 months old n its in d service center for more dn 2 and half months. i hope that you people will take an action against it . and i wont accept my mobile if it has even a singal scratch . as my mobile was brand new . if i dont get my mobile with in this week . i would file a case against SAMSUNG in a legal way . hoping for good kindly do the need full
