Flipkart — the attic sheesham wood solid wood tv entertainment unit

I ordered the above mentioned unit on 05/10/2019 and paid rs.8699/- online as mentioned in the price. Yesterday when i was just going thru flipkart items i came to know that the same unit is available for rs.6399/-.
I called up flipkart customer care and asked him about it. He said it is the sellers wish at what rate he can sell the item. I asked him to cancel the order as i have not yet received the material, it is supposed to be delivered on 24/10/2019. He said order can't be cancelled. I asked him to refund me the extra amount paid. Which he said can't be done. One can understand a difference of 5 to 10 % but not this much.
This means the seller has unfair trade practices and to which flipkart also is encouraging them. This amounts to cheating in a way.
I would like the concerned authorities take proper steps to regularizes the e-commerce business against unfair business practices like this.
Again i don't know the item i ordered will be delivered as per the description mentioned on website.
I would like action to be taken on flipkart and the seller to refund me the excess amount paid for the item.
