I have submitted my redmi 2 mobile on 25th july for service to be done by service center but they havn't done yet. When i called them they said parts had not came from the company side.
I am very annoyed with this type of services provided by the xiaomi india service center in lucknow.
Delivery dates given by service center was 9th aug, 2016 but when we again call them on the number which they have given they didn't pick up the call.
