My mobile phone (Sony xperia dual E4) was having some serious problem from 7th day of purchase of my mobile. On 8th day i submitted that to Sony service center at connaught place. In initial check up they said your mobile would not be replaced as it crossed 7th day. And company's return policy lies with in 7th day. So i agreed to repair my handset but when technicians of that service center scrutinise my mobile thoroughly then they said to me it would be replacable with special approval required to respective authority of Sony mobiles. I submitted each and every accessories of my mobile which i got along my mobile to service center for replacement of my mobile ( charger, head phone etc). And they assured me to got my mobile replace with in 5 day. After 5th day when i called them then they stretched 5 days more .
