Sir i had submitted my sony xperia handset model no f5122 in the service center for replacement. I just have used my mobile for a week and i notice that my phone has issue. Service center told me that my phone they had taken for replacement and it will come soon in 2-3 days. Then they said they need 15 days. They daily fool me that i will going to recive my phone in 2-3 days. But nothing happens.
