Yu Yureka — Phone camera not working

Address:

Hyderabad, Andhra Pradesh

I brought YU YUREKA phone in february 2015. and now the mobile's rear camera isn't working. Whenever I on my camera app, the screen goes black and thus the app closes. Thus for this I approached yureka customer care support many times, as they promised to give door to door service as there are no service centers. I have sent mails and called them many times but there is no further response from their side. Whenever I call them, they give me the assurance that they will provide me the solution for it, but they don't. The camera app is not working since two months now, but still there's no solution provided by the yu yureka company and my phone comes under warranty.
