[Resolved]  Flipkart — dell vostro 15

I have purchased a dell laptop on 14 oct, flipkart delivered the product on 19 oct. On the day itself i made a replacement request, as the product is having manufacturing defect. The technician visit date given was 26 oct, but no one from flipkart has contacted me on 26 oct. I called 5 times and wrote mails but my issue was not resolved. Finally on one call flipkart has given the technician visit on 31 oct but no one from flipkart has contacted me on 31 oct.
