Dear sir
I have purchased sony xperia t3 mobile phone on 10/01/2015. From starting i have a issue of battery backup problem. After several visits to sony service centre problem of battery drain not resolved. At last on 04/07/2016 i handed my mobile phone in
Sree balaji electronics (Sony authorised service centre). Still now there is no response. And now the service engineer is telling me to pay 21000/- rupees for exchange for an another mobile phone because the company has no stock for mobile battery. Sir i have buyed sony xperia t3 for 20000/- and again 21000. Sir i can pay only 25%of my mobile coast for another mobile phone. Please resolve my problem as soon as possible
