Flipkart - Package not delivered

I had order a mobile phone (realmi *i - Space Black ** GB) on **th Jan through Flipkart and the order was confirmed with the delivery date as **st Jan.
Since **st Jan, i have been receiving calls from customer care daily without fail saying that the order has been delayed and will be delivered asap until **th Feb. Suddenly only **th Feb, they have cancelled the order without my permission and saying that the order cannot be delivered. This is very unprofessional as they have made me wait for ** days on a item to be delivered on **st Jan itself and without any concern they have cancelled the order without my permission.
I demand the order to be delivered to me at the same price at which i have ordered (***** rs) and need to claim compensation of the mobile price for this unprofessional behaviour without any concern for the customer need.
