Apple India — Apple iphone 5S

Address: 500094

I bought a new iphone 5s on 14 feb 2017, and since last one week the touch is not sensing at all, when i gave it to service centre here in hyderabad, they say that there are dents in the phone hence the phone touch is not working and they are saying that the phone cannot be serviced at all and device replacement is the only option (Note: the phone is under warranty and since the phone has dent it was not covered under warranty.)
