Address:

Madhya Pradesh

using mobile of samsung company. When I buy this mobile this mobile seems to good to me but on later when I connected this mobile to computer and wanted to use mobile to computer for internet work but mobile always says "failed to connect" and hanging problem so I gave this mobile to samsung office to make this problem clear.
But they do not done anything they simply format to it and says to me that it is ok. But later on when I check it again says "failed to connect" to computer and hanging problem also goes on. I have many time call to them but says to me that it is computer problem. Time goes on and no solution.
Time has reach to out off warranty of mobile.
So I also write this problem to samsung mobile web site they again take my mobile and again format it but no result the problem goes to continue. So I again write to them on samsung mobile web site.
They again take my mobile but when I take my mobile I again say to them that my mobile says that "failed to connect" so please check my problem in front of me they check the problem and says to me that we cant solve your problem.
So I says ok and I use mobile again but now new problem have arise that
mobile automatics switch off and battery problem.
Hanging and mobile problem goes on continue....
so I again write to them but this time they are avoiding me.

And I also tell that I will complaint about you so they simply says to me that "jo kar sakte ho kar lo"
