Flipkart — Flipkart hasn't delivered my product

I purchased a laptop from Flipkart for ₹52990 and my bank debited a transaction fee of ₹903 for this purchase. But flipkart confirmed the order and breached the order delivery twice and now they don’t even know where my product is. I’ve waited foe 20 days and missed an interview because of not having a laptop. I can’t cancel the order also, because if i cancel the transaction fee debited by bank will be a loss for me. Flipkart is responsible for that money as this delivery issue is there responsibility.
