HTC — Company asking for 24k for under warranty set

Address:

Shimla, Himachal Pradesh, 171001

I have htc one e9plus which has a problem since I have this mobile it automatically shut down & takes hours to get started again. I have got it repaired thrice from the service centre but every time I faced the same problem then lastly htc picked up my mobile for the repair & returned me back after so many days that my mobile has a small crack on the body hence I will have to bear 24k rupees to get it repaired in spite mobile is under warranty. I am fed up & getting harassed by the bad services of htc . Pls take my matter forward & help.
