Micromax B 1 Mobile - Phone warranty not given by company under warranty period

I hereby declare to that micromax has fraud with me .I bought micromax *b through online * months ago .it had warranty period of * year as usually like other handset. After just * months of use ,it gets disfunctioning.firstly finger sensor not working after couple of days when I visited service centre for claiming warranty of finger print sensor afterwards phone screen getting blurred or buffed nothing can be seen properly.i am suspicious that service centre is also behind it because when I visited there they refused to repair under warranty and asked to charge .they took my phone for a while and I was not able to see what they did inside with my phone .I also complained several times after that to customer support service but yet not even a single step taken by them and don't reply effectively. I hope you may consider my issue .Please draw the attention of concerned authority through your esteemed platform.i am sending screen shot of conversation to customer support .
