Flipkart - Orders cancelled without proper reasons

I ordered a product on July * from a seller on Flipkart, which eventually got cancelled by them after two days, without even a proper reason. After that incident, I ordered a gold pendant from another seller on July *th, which has now been cancelled after ten days. Please note that it was not out of stock at the time I ordered it, and my order was 'approved'. Now, Flipkart is telling that it was a technical issue with the seller and I can now place a new order. But, the product has gone out of stock now and its price too had risen considerably over the days following my order. Flipkart would provide a refund, that's not the point here. At the end, only my time and efforts have got wasted, and there's also an opportunity cost linked to this. Would the seller cancel the same order if the product price had decreased? This is completely unethical and seller cancellations have become so common in Flipkart. I'd like to get the product at the same price, as the resolution.
