Flipkart Private Limited - Flipkart Fraud seller Indiflashmart and Bad service of Flipkart

I order product SAMSUNG Galaxy Tab S* FE+ * GB RAM *** GB ROM **.* Inch with Wi-Fi Only Tablet (Gray) from flipkart at price Rs **,***
Seller: Indiflashmart
Product order date **nd October, ****
Shipping date *th November, ****
Later changed to *th November, **** after address change
The order got cancelled by the seller on *th November, **** with reason - Seller ran out of stock for this item soon after you placed your order.
The seller took * weeks to know that he dont have the product in stock which he claims even though same can be seen available on flipkart website

The product is still available on the website with increased price with the same seller.
This suggests fraudulent practices by the seller.
When I researched about the seller on web there are many fraudulent cases similar to this and yet flipkart is not ready to take any responsibility for the same

When I first call flipkart customer service they said we will provide you the coupon to match the same price with which I order. Later I got message from the flipkart support that they will provide just a Rs *** coupon after the same product with the new available price is ordered, which was Rs ***** with the same seller Indiflashmart.
Later again when I called flipkart support they said they cant do anything about this you will need to buy the product as the available price or wait for another offer, When I asked them to speak to the seller they mentioned they dont have any contact details of seller.

The price difference the order which I placed earlier and the new price was around Rs *****

Request to flipkart availing the product for the order price was not fulfilled

Also seems flipkart is in coherence with Indiflashmart seller for fraudulent practices to just show that they have product with less price and later cancel the order
