I have placed an order for sofa set on 15th august, 11:56 pm, flipkart order id: od[protected],
And order is just approved now and seller is still not started processing my order not even it is packed or shipped but when i tried to cancel my order it is saying you can't cancel this order.

I have also contacted to flipkart customer care but they said they can't help in this.in flipkart cancellation policy it is clearly mentioned below:

How do i cancel an order?

You can cancel your order online before the product has been shipped. Your entire order amount will be refunded.

In case the item you have ordered has been shipped but has not yet been delivered to you, you may still cancel the order online. Your refund will be processed once we receive the originally ordered item back from the courier.

Unfortunately, an order cannot be cancelled once the item has been delivered to you.

In order to cancel an item in your order:

Log into your flipkart account and go to the 'my orders' page
Identify the item you want to cancel and click on the corresponding 'view details' link
In the detailed order page, you will see 'cancel' links against each of the items in that order
Click on the 'cancel' link, indicate the reason for cancellation, choose a mode of refund and confirm cancellation
Once your cancellation request is created, we will ensure that the cancellation is processed as soon as possible

But they denied to cancel the order even they have mentioned this in policy.

Please help me to cancel this order.

I am attaching screen shot of policy and order details.

Thanks,
