Flipkart - Package cancelled without permission

There was a sale on flipkart on **rd of June and my preferred items were on discount which is why I placed an orders for * items. Without my permission, they cancelled * of those citing logistical issues due to Covid. The thing is, they could have just delayed it if they were facing issues. I also have orders placed on Amazon and Myntra which have simply been delayed. Now they are asking me to place an order again at the higher price. This is harassment as company policy should protect the consumer against such behavior by sellers.
