[Resolved]  Flipkart — product not delivered, forcing me to buy the same product at increased price.

I ordered a shoe for ₹2877 from flipkart. They didn't delivered it on time and now when the pricing has increased, they are forcing me to cancel my order and place a new one at increased price ie. @₹3188. I already paid flipkart and now when i called them, they are saying me it wasn't delivered coz it is out of stock/ address mismatched. This is not fair i always get my product delivered on same address. I asked them to raise a complaint against seller or courier service provider but they are saying me "we can't do anything and your problem is resolved." which is not resolved yet, i asked them to provide me the same shoe at same price.
