Xiaomi India — i am complaining about my experience in xiaomi service center ranchi

Address:

Ranchi, Jharkhand, 834002

In "6-10-17" i had buy a new xiaomi mi max 2 at 15900 and 2 day ago i had updated to miui 9 and i got 3 issues of
1. Notification light not working anymore
2. Auto brightness is also not working
3. Some apps closed it self or getting lag.
Mi service center has told it has some system part issue so in 1 month i could a new phone damage so they told me wait for 1 week and when i asked them what's the exact issue but they only says that system part is not available. It was a new phone i am very disappointed this company phone's
