Flipkart - Order cancelled by seller

Yesterday I have ordered LGXboom ok** and payment also done from my credit card. Today I got an email. Seller cancelled my order and gave reason out of stock. However, my brother also ordered the same item after my order and his order got shipped if his order got shipped so how possible my order out of stock. Now the same seller increased the price of the same item. Earlier price was **** now price ***** its a major complaint I spoke to Flipkart people. Nobody able to help in this complaint they just have an answer will speak to the seller and you can place a new order. I asked who is responsible for the difference amount they said we can only refund **** rupees for the new order if price difference more than **** then we cant help. Horrible experience with Flipkart. The new price is ***** for the same order after the cancellation of my order. My order id OD******************.
