I gave my phone to service centre more than a month ago in chnadigarh.
Their landline is not working so there is no way to contact them.In the past 50 days i ahve been to their office 6 time and everytime they say they donot have the parts and its not serviced.
They said yesterday they do not know when the parts will come and they suggested i goto to delhi and get it done.
in the month that they kept the phone with them selves the warranty time period expired.
As they were not sure if they can fix the phone, i got it back .
It the service centres fault that the phone is not fixed and the warranty is expired.
who can fix it. the warranty expired on their watch. I am planning to raise a harassment case against xiomi and the service centre for such unproffessional conduct .

I have field an online grevience : DARPG/E/2016/13156 against Xiaomi
