Flipkart — Privacy issue - Delivery staff viewing orders and then Cancelling

I ordered a Titan watch in Flipkart on End of Season Sale offer in the end of July 2022 with 85% discount as prepaid order. This has been shipped on the same day by Retailnet Bangalore and was Out for Delivery the next day at 08:30 hrs through EKART and this has been marked as DELIVERY UNSUCCESSFUL at 12:30 hrs "Unable to attempt delivery due to operational issues" - this is the status that was shown on the EKART LOGISTICS for that consignment number. When I approached the delivery staff next day why the above mentioned order was cancelled - the delivery boy clearly said as the SALE PRICE was VERY MUCH LESS THAN MRP, his SENIOR MANAGER in the Padi Hub has cancelled the order. Why delivery hub people are viewing the order details which is a privacy and the item may be private for some customers. I have all the records which clearly proves the above. My complaint in the Flipkart's portal still remains unresolved. Can we conclude that above is the truth behind FLIPKART'S End of Season Sale, BIG BILLION DAY SALE, etc?
