Flipkart — Cancellation of order after 10 days

First of all they show heavy discounts on goods to attract user then blocks the user to buy the same if in case you have luck and try to grab the deal and successfully place the order they cancel it without informing or any proper explanation (as viewed on the site) concern is that why false data is shown to the consumer
order placed on 21 sep delivery expected date was 28 sep still the product wasn't shipped have more order on the same day as of 21 and recieved them on 27 but for this it was the deal which grabbed by sacrifing the sleep
and these is doen for 2 products
