Sangeetha Mobiles — damaged phone

I have bought a phone last year in in april month at sangeeta marathalli shop. One year is not yet over. I have spoken to sales person 2 weeks back only but there is no replacement for my phone. If people are not taking responsibility then why we should take insurance? This is not a right way to talk to respond to customer complaints. We come to sangeetha because of different options but when i am in need nobody is responding.
