Ordered allie wood sheesham wood solid wood 6 seater dining set (Finish color - brown) - od[protected]

Placed this order on 9th of june and 27th of june is the delivery date but it never got delivered and seller directly calling us to pay extra rs. 1000 to ship that product. I don't want to pay 1000 and i already paid 400 as delivery charges while placing the order.

I tried to look for an option to cancel it, unfortunately, the product could not be cancelled. Even flipkart customer care is not responding correctly for cancellation of the order/or in delivering the order.

I have already paid complete money to you, for which, i have paid the 1st emi to the bank too, for the product which is not delivered.

Updates in app shows that product will be delivered in next working day since 27th. Till now 5 dates has been changed and product is not delivered and seller and logistics person are calling me to pay 1000 and they are saying unable to cancel the order from their end.
