[Resolved]  Sony — sony xperia z ultra Damage in sony customer care

I am a practicing advocate in Madras High Court. I purchased Sony Z Ultra on 19th November 2013 for Rs45000(prevailing price then). I purchased online through Flipkart. However on 26th of this month June, 2014 suddenly the phone went blank and frozen.Immediately I approached their service dealer in Chennai, Repair and Return Technology Pvt Ltd, Pantheon Road, Egmore on the same day. I explained the issues. They took my phone and gave a job ticket no:W[protected] and after examining my phone they promised to deliver on the same day. I waited nearly for 4 hours on 26/06/2014. However in the evening they asked me to come there on the next day to get back my phone. Hence on 27th morning I called them but they asked to call in the evening. But for one reason or the other every time they used to ask me to call now and then. Even after 5 days the mobile is not delivered to me. They are avoiding and simple dodging this issue. I never thought sony will cheat people like this. I am really worried. If this is happening even to an advocate, I shudder to think what is the plight of the common man.
Sony must have replaced my mobile with a new one or atleast refund my money.
