Micromax — Battery Complaint

Address:

Srinagar, Jammu and Kashmir

I hhave purchased a micromax canvas knight A350 in the month of January. But a week before I got a problem with the battery same was conveyed to micromax service center on 20/06/2015 for which I got the proper receipt. Which is lying with me. They promised me that yothat you will get the new battery within a week. But its now been the 8th day and I didn't get the battery yet. This caused me a huge inconvience and losses because I have no other cell phone. So kindly take an action against the micromax care service center situated at karan nagar srinagar
