Flipkart — Fraud Exchange scheme and useless delivery time

Delivery Time
1) Moto G 82 5G : I have ordered it on 01-Aug and Flipkart confirmed a although very late delivery time of 07-Aug. I still patiently waited till 07-Aug. The useless tracking system on flipkart site was not showing any clear updates till 08-Aug. On 08-Aug, Flipkart changed the delivery date to 14-Aug. When complained to the call center they informed that order cannot be cancelled as it is in courier. I have anyways cancelled the order and got the return. But very horrible waiting time and no improvement at all.

2) I ordered Moto G31 on 08-Aug ( Still wanted to give Flipkart a chance) in exchange of Samsung J7 which is absolutely fine working with minor scratches only on back panel. The phone exchange value was Rs. 2350 which is surely high and I was expecting some reduction of Rs. 500 at the time of exchange.
However to my horror, the delivery person who visited home started finding out issues and informed that there is screen discoloration. I am using this phone and has got very good display. but I decided not to argue since AS PER FLIPKART OFFICIAL PAGE, IN CASE OF DISCOLORATION, VALUE IS REDUCED TO RS. 1850 which was still acceptable to me. Now the fellow further informed that there are scratches on screen !!! I still accepted it since AGAIN AS PER FLIPKART OFFICIAL PAGE THE VALUE IS FURTHER REDUCED TO RS. 1500. I still accept it but under the fraudster exchange scheme, the delivery fellow has informed that value of the phone is combinedly reduced to only Rs. 700!!!
IS IT A WAY FOR COMPANY LIKE FLIPKART TO CHEAT CLIENTS?
WHY YOUR OFFICAL WEBSITE PAGE DOES NOT MENTION THAT THE EXCHANGE SCHEME PRICING SHOWN IS ONLY CHEATING AND YOU ARE INTERESTED TO PICK UP THE OLD PRODUCT AT SCRAP RATE?

I have requested the delivery person to stick to their own valuation scheme of Rs. 1500 or otherwise I will cancel the order. He happily opted for cancellation of order !!!
I was long time member of flipkart plus but it seems the success has now gone to the head of flipkart team and they simply do not bother for deliveries, and fraud exchange schemes. Good bye flipkart!
