Flipkart — delivery not done as per promise date

I am writing this with very upset mind as I am very much frustrated with the services of Flipkart and their courier partner.

I ordered Apple watch on 29th Sep as on 2nd Oct, it was my birthday and delivery expected was 2nd itself.

My order is lying in Jaipur warehouse from 1Sep 1:24pm and no movement after that.

I have connected with customer care but of no use, they just make excuses.

I have escalated to twitter and everywhere but of no use. I have escalated to ceo, customer service head and all top management but dont see any revert.

Today, it is 8th October, there is no update and Flipkart today tells me cancel order.

Biggest mistake of my life to purchase with Flipkart.
