Micromax — Company did not repair mobile even during its warranty period

Address:

Mumbai City, Maharashtra

I have purchase micromax X088 mobile phone on 18 Feb 2016, however in few days after purchase it did not work properly, there was some defect which was not due to our mistake, I went for repair of mobile in our nearest micromax gallery which is in mira road at shanti shopping centre. however they refused to take my phone to repair even though it was within its warranty period saying that the manufacture of such phone is not done since 2000 and the seller has fraud me, which is totally not acceptable because the manufacturing date mentioned on the package of the phone is August 2015.
I have escalated the matter in micro max gallery but they have refused to consider the matter.
