I have ordered an item from flipkart on 21st january. While tracking my order it shows that your order will delivered to you on 23rd january. But when it comes. I don't know what's happen, and while tracking now on flipkart it shows your item have been delivered but i didn't receive my order yet. What is this. I have try lots of item your toll free number but it does not exist. Plz mention your correct toll free number. Very very worst service of ekart logistc.
