Sony India — To consider Warranty for self scratch (Hair line scratch) screen

Dear Team, My self Mayur Saraiya from Surat, Gujarat and I have purchased Sony Xperia Z Ultra from an authorised Sony dealer (Tech One Enterprise, Surat, Gujarat, India) on 17th Feb.'2015. I have hardly used this phone for 2 months. One day (on 10th April'15) I show hair line types of scratches on my screen and my screen becomes unresponsive. I would like to tell you that neither my cell phone had damage nor it was fall accidentally since the time I purchased my handset. This was clearly a self scratch on handset..!!! Yes... Self Scratch..!! But I didn't have any proofs to prove them. I visit the shop (11th April'15 at evening and then 13th April'15) and then the service center for to claim warranty. The service center people ask me that it is damage one and it doesn't falls under warranty and you have to pay us 50% to replace this handset with a new piece as its a non-repairable, I didn't had any Idea that this handset is non-repairable. I have submitted my handset to replace with new one and they are telling me that I will have to pay some[protected], as it won't come under warranty. Since I have not broke it, and it has been broke it self only may be due to quality of screen of the phone. My JOB SHEET No is. W[protected] It is quite huge amount for a people who hardly earn 12000 per month and bought a phone on EMI just as he thought to use for a longer period of time. Now when I searched on google " xperia z ultra screen scratch so fragile" for the solution, I have came to know that this Z series of phone has a self scratch problem universally. They have replaced some phone in abroad. So why can not they replace me a new handset since its 2 months old and also not damage from my side? I would request you to help me for the same and consider my claim under warranty so that I can get a new piece in replace like they did in past with some of the customer. You can check their complaints for this screen on there own website, which proves that their products has problem on its own.
