Karbonn Mobiles is the worst company I have ever dealt with. I have bought my phone in January 2013. After using it for 2 months it stopped working completely and then I went to a service centre. That service centre refused to service it saying they do not service phones sold from Bangalore (even though it is a national warranty). So I went to another service centre and gave it there on May 18th. They people at their service centres are also very arrogant. They took 2 months to service it and the same day I got it back it still gave me problems. I have been using it since end July with these problems and Karbonn never answers calls or replies to emails. After making consumers aware of their poor service and very badly run service centres in dilapidated buildings, they blocked me from their Facebook page. I have been harassed a lot by this company and want some justice. I want my money back. Please help. I have lost a good amount of money (Rs. 8250) and have been facing problems since I bought this phone. I am not willing to give the phone to the service centre again as I do not have a spare phone. I WANT MY MONEY BACK!!!
