Xiaomi India — cheating the customers

Address:

Hyderabad, Andhra Pradesh, 500081

I purchased redmi 4 and within 3 weeks my mobie fell down and display is slightly got cracked and i given in mi authosised service centre.
Address: plot no. 44 & 45, opp. Mercedes benz showroom, near madhapur police station, kavuri hills, hyderabad, telangana 500081
The people lives in hallosination and and not even know the prices for what they need to charge and they dont bother.
Coming to the story...
I have given my newly broken redmi 4 mobile for change of display the mobile is fully working in condition and i am using the mobile. Before going to the store i called those service center people and enquired about the cost availability and went to sore in 30 minutes.
When i went to store one of the employe took the mobile and given acknowledgement and i went home.
When i reached my home these service centre guy calls and tell that we do not have that part (Display) available and they dont know when it will come again i asked them to keep order also. The people says dont know...
Then i went to store again to collect the hand set... Then another story begins... They asked to wait for 3 more days to get the display... Then i told that i can wait for 7 days also but there is no proper communication from the people.
Then i felt that this is not going to work no longer and asked to return the hand set. They agreed and about to return the handset and asking to pay rs.120/- as service charges...
Then i was surprised like anything they way they treated me...
My scenario clearly says that to replace the display thats all and what these people do in checking the display.

Bottom line:
These people are cheating the customers like anything and they dont even bother.
Lots of miscommunication
No proper knowledge...
