Xiaomi India — sudden hanging of touch, can able to receive call but cant lift, only power and volume buttons are working

Address:

Guntur, brodipet 4th lane, Guntur, Andhra Pradesh

Redmi note 7 pro mobile, i bought 2 months ago, sudden hanging of touch was the main issue with the mobile at the time of hanging, went to sevice centre 4 times for same issue but they register the complaint two times. The service centre is not cleary telling the problem, once they changed finger print part and took the phone for a week, now they are telling its display issue and till now they din't return phone till now. I am deeply disappointed with mi servie centre in brodipet, guntur. So i request you to please consider the issue and solve it quickly.
