I bought Sony ZR on 11.08.2013 and within one month the mobile had some complains so Sony replaced the handset. Now again the phone is not working properly and I have asked for refund but I am getting a reply that my request is declined. My warranty will expire on 11.08.2014 and I dont have time for trial and error with the mobile. I want refund of my phone and want to escalate the issue to the top most officer. The customer service had also offered me replacement of a higher version phone but now they are not giving me that option also. The service of sony is poorest.
