Sony India — sudden death (DEAD)

Address:

New Delhi, Delhi

Hi, I am having a Sony Xperia C mobile. Overall quality and performance of this mobile is good, and I am satisfied with it, except the concern of sudden death. It suddenly gets switched off anytime and does not gets On. I have also visited the Sony Service Center 5 times, but still the problem persists. The Service Center executive make the problem gone just for sometime. After a couple of weeks it again creates the same trouble. The date of purchase of this mobile is "2nd Of March, 2014". Its just about 4 months only after purchasing and it has been submitted in service center several times, I am bearing the loss of my data everytime whenever it goes to the service center. I just want my mobile to be replaced with a brand new set with no manufacturing defect. I am attaching the job sheet of the service center. A line in response would be appreciated.
