Flipkart — Delay in delivery for one-day and two-day delivery

Website:

www.flipkart.com

Ordered 3 items on Flipkart on 7th August with two products with 1day delivery option stating that it'll be delivered within August 8th 2pm. And the other order being delivered on August 9th with two day delivery option. On August 8th, the delivery date of the first two products changed to "item yet to be delivered". The other one changed to "delivery by August 12th".
After contacting customer care, i was informed it was a logistics mistake (same mistake for another product that i cancelled after waiting a week after the expected delivery).
