Consumer Redressal

I would like to share my dissatisfaction with the after sales services provided by Sony and its authorized service centers. To share, I am using Xperia J for almost 11 months now and having problem of Auto Restart and System n Game lag from May’13 onwards. I have had gone to service center and had it repaired thrice at Accel Frontline (Shivaji Nagar, Pune) but noteworthy the problem is still persisting. However I agree, they did change few of the parts of the phone to resolve the issue but nothing has really worked. My system restarts on its own once a day and I cant play any game on it. Dismayed to listen to service center’s spokespersons reply on this that Xperia J isn’t compatible with any game except less than the memory 10-15 MB (phone worth 16.5 k isn’t worth of playing games on it of memory 30-45 MB). I feel cheated wrt to quality promised by the company with the product and been delivered. I request you to please help getting it resolved asap.
