Flipkart — Non delivery of products in time which it is promising

Address: Ernakulam, Kerala

Sir, I have booked three books on 3 july 13 and flipkart online service showing that it will be delivered by 06 july. But today is 11 july and Still I have not received the same. After contacting their costumer service they are telling that it will reach by more 2-3 days like that. How much time one can wait ? If some exam is coming and somebody has ordered books form them then it is how much great loss of time for waiting for false claim of flipkart service. pse take action for these fraudulent companies.
