[Resolved]  Flipkart — order which is placed successful is cancelled by seller

In flipkart there is are offers in sale like "buy 3 and get 10% off, buy 2 get 5% off"

These offers are completely fake.
I tried to place 3 units of boat earphones but i got a popup that i cannot place 3 units of same and asked me to choose another product from same seller.
So i placed 2 boat earphones and 1 bolt earphones from same seller. The offer got applied and i got 10% off during payment but after payment is successful seller immediately cancelled the order.
When i checked with flipkart they told seller is cancelling inorder to give each customer equal opertunity. But the fact is i didn't place atleast one order in flipkart in this sale.
Flipkart people just asked to wait few days and place order.
I tried multiple times and everytime the same thing happened. My money got deducted then my order got cancelled and refund process started.
