Flipkart - Flipkart cancelled my order 3 times

I ordered a Realme*i phone, flip cover and tempered glass via Flipkart (order ID: OD******************). The Realme *i as delivered rest items got cancelled saying some stupid reason like “Due to the huge demand of products and to provide customers with an equal opportunity to avail the said deal".
I reordered the same items. This time from different sellers and different brands (Order ID: OD******************). It got cancelled again for the same reason. I tried calling customer care. The guy who spoke told the same reason. Then I ordered for the *rd time again (Order ID: OD******************). I even chatted and mailed the customer care executives. Each time this happened and they seemed to be very irresponsible people. My order got cancelled thrice now. It is a very humiliating experience for me what Flipkart has done. I don't understand why they are doing this. My precious time has been wasted for this. For over a week this has been going on i.e me ordering and waiting for the shipment of my products, only to hear after one day that shipment is cancelled by the seller. This is very disappointing and humiliating for me as a consumer. I hope I get justice of delivering the products which I ordered. I am not asking for any compensation for the time that I have lost but I want them to show some justice by not cancelling again. This is because I want the stuff I ordered. It's very important that's why. Please kindly look into my issue.
