Xiaomi India — repair of a handset

Address:

Jammu, Jammu and Kashmir, 184120

A have bought redmi note 4 handset online few weeks back. Suddenly the touch of the display stopped responding. As i rushed to customer care centre. They don't paid much attention to it and refused to repair the handset with an excuse that "your motherboard is effected by water/liquid so you have to pay 10k to repair this". There is no such instance infact. I am very upset by the callous behaviour of the staff as well as the after purchase service of xiaomi. So i humbly request you to kindly repair it completely or replace it.

Thank you.
