Flipkart — Delivery issues, exchange policy, complete year protection

On BBD sale, flipkart mentioned some conditions for the exchange of device. My phone fulfills the conditions but the wishmaster still rejected my phone on baseless grounds and when I tried to clear the issue with him, he was so rude and he was threatening me that he will cancel my order and was very rude in speaking, I went to the ekart office and they also didn't helped me. Now I'm forced to pay the exchange amount to receive my order.

Also, flipkart is telling me that I'll be able to purchase their complete year protection but they are not providing it and neither I'm getting any help from their side.
They are just some greedy people who are looting everyone and once a order is placed they are giving the most pathetic service they can.
In the BBD sale they are showing the price of samsung galaxy f41 as 19999 and then reducing it to 16999 just to fool people wherein reality the base price of the phone is 16999.
Fed up of flipkart and I'll make sure that no one known to me orders anything on flipkart.
