Flipcart online shop - Flipcart cancelled my orders

Yesterday (**th July ****) I ordered ** shoes from flipcart, out of which I received the delivery of two shoes at noon on **th July. And out of the remaining shoes I canceled the order of * shoes on **st July evening, just ** minutes later I saw that all my orders were canceled by flipcart. Why did Flipcart cancel my orders, and if they cancelled then why did they receive the orders? If all my orders were canceled due to my cancellation of those * shoes, why was I not warned before the cancellation "If you cancel these orders, your all orders will be cancelled". Either my orders are delivered or else, I am seeking compensation from flipcart for my time and harassment.
