Flipkart — Order cancelled by Flipkart just before the day of delivery

Hi, I'm Piyali Paul. I booked my order on pre-book deal in this big billion day season. Flipkart cancelled my order. Order IDs are OD[protected] and OD[protected]. I tried calling customer care, she said that my address is wrong. How is this possible? I got many orders on this same address. All the orders price hiked. Now they are saying there no other option rather than placing a new order. If Flipkart does not want to sell at lower price, then why they are saying sale? I'm very disappointed this time.
