Xiaomi India — bad behaviour by customer centre

Address:

New Delhi, Delhi, 110053

I was went to mi krishna nagar service centre for registering a second complaint against red mi note 5. It's not working properly from since starting. When i submitted the phone for repairing, they didn't told me estimated time for it. Whenever i asked for how much time it will take, they always said just 10 min, 15 min.
And when i asked for how much time it will take finally, they replied very badly and said just sit there, it will take 1 hr more.
They took around 2.45 hrs for repairing just it's screen.

I realy had very bad experience mi and it's team.
Shame on you guys.
