Well I am a big fan of sony technologies, but the same can't be said for the service quality of Sony's service centre.
My device was doing fine from past 2 years, and had some issues in December 2017, paid more than half of the price of the phone in the name of trust of sony where I could have bought another phone adding some more money to it.
And after that device's visit to service centre started. And now the device is completely dead by May 1st 2018.
My device was with the service centre more than me. N all in vain as I was asked to pay again the same amount for it.
