Sony India — xperia x dual heating issue

Address:

637104

I have bought a new xperia x mobile on april 26, 2017. It was very heated when i using camera.. And also am already give it the service center but still now the problem is not resolved... When i ask to the service center technician he told this mobile is failure model so can't resolve this problem like that... Now what can i do... The mobile cost is 25000.. So i can't ignore this mobile... Kindly tell this model is failure model? Really am very disappointed with this mobile..
