Ekart Logistics — Product not delivered

Address: Bangalore, Karnataka, 560032

I ordered a hp laptop and i was said that it will be delivered by 4. nov.2016 and i got a text on 1. nov.2016 stating that the product will be deivered but after waiting the day long the product wasnt delivered. if they cant deliver the product on texted date then why do they send such text messages and trouble the customer if i was asked to rate ekart i wouldn't even give a single star for there fraud service.
