You need to escalate this issue with snapdeal only ... And not directly with micromax because they were seller and its there responsibility to provide you defect free product as per your order.... Please post it on their FB their social media team is very prompt ..... Explain them full situation without hiding any thing ... Leave your number and ask them to call back.... Be assertive but not aggressive when you speak with them.... I am sure they will replace your LED also you can claim compensation from Snapdeal for the agony you faced... Last time I had a annoying incident with SD they send their apology with 1000 INR voucher on my account... All the best......
