They had taken one month for repairing but after getting back to it again its goes under problem with display on next day. Then I had given to sony service centre at Rajkot and they had told me that my issue will be solve in 10 days but after 21 days means till now i didn't got it back from service centre. They gives date again and again but not solved my issue till now. I'm not satisfied with your service. It's a very poor service and which not suits you as a reputed brand so that I can't suggest to anyone to purchase your handset if you providing poor service like this because this is not worth. So i request to replace my handset as soon as possible. My service Job Sheet number is W116071000423 which is dated on 10th July 2016 and IMEI number of my hadset is . You can contact me on. I hope you will give positive response. Thank you.
