Sony Mobiles — Xperia m5 service

Address:

Indore, Madhya Pradesh, 452001

I bought a phone xperia m5 in feb 2016 which automatically shuts down on it own accord and became dead on 5.08.16
I gave the mobile on the authorized service center they took my mobile for out of warranty repair saying the glass back is cracked when i later on checked up i found it is a common problem occurring in the phone model m5
The service center is higly uncooperative and unreachable
There is no other centre also
They refused to help when the problem is of software n internal and within warrenty period
Even long delay and line is a comon problem at the center
