Worse service from MI customer care
call is not connected to toll free number
if connected wait for 15 minutes and call get automatically disconnected

the thing is if you go to service center at 6 pm they said it is closed while on the door they wrote working hours is 10:00 to 6:30

Another thing is asking them give another number to call they said call the toll free number i have dialed se result waiting for 7 minutes and call get disconnected

The mail i have sended to them woth same query there is no reply from xiaomi

After asking again givee another number to call or register my complaint about call not get connected and no reply from email he said i m not from mi i am from TVS ...lol what the hell thia is the reply from mi service center and on the door they write authorized mi service center
