Address:

Dear sir /mam,
I am writing this email because i don't want to use sony mobile which was i bought 3 months ago. The piece was faulty i already submitted it into service center 15 days earlier, yesterday i received my phone but now it becomes worse. I don't understand why u people create such # phones. I want my refund as early as possible.
1) model - sony xperia xa1 (Black 32 gb)
2) purchase date-24/6/2017
3) from the date of purchasing i suffer software related issues. My phone frequently goes into vibration mode so i continuously visit sony customer care regarding the same issue but they told me i had to wait until new software come i wait for 3 months but issue not solve (Sony customer care — zeal infotech, g14, 15, c1, jayaram complex, neugi nagar, panaji-403001 goa)
4) at 12/09/2017 i again visit customer care regarding charging issue.. (Ticket id - [protected], job no. — w[protected], product submitting date-12/09/2017 product delivery date - 26/09/2017)
5) now my mobile suddenly goes switch off. Last night the mobile battery was 82 % and at morning it switched off then for charging it took 6 hours and now battery was 52 % then again goes switched off and now charger also not connecting to mobile.
I just fed up to continue visiting the service center. So i don't want this piece and i want my money back.
