Flipkart — Order cancelled by Flipkart without my consent

OD[protected] is the order I'd which was cancelled by Flipkart showing reason for cancellation as seller went out of stock.

Completely false claim as seller and Flipkart still selling same product at higher price.
Also, product was already shipped and in transit before Flipkart cancelled my order.
How is that possible Flipkart.

Stren action needs to be taken against these ecommerce companies for fooling people and breaching sales contract.
