Flipkart - Iphone 12 Red not Delivered

I ordered iPhone ** **GB on *nd Oct'** in Big Billion days Sale Order ID: OD******************. The delivery date was *nd Oct'** which got extended to *th Oct'** . Till *th Oct'** to **th Oct'**, I repeatedly mailed and called them to deliver my order. They were not even giving any expected delivery date after *th Oct'**.On **th Oct'**, Suraj Rohira from the Flipkart support team called me and asked me to cancel my order and place a new one at a higher price. I accepted his offer because he cited the issue that my shipment is stuck in the mother hub and could not be delivered. So on **th Oct'**, I placed a new order ID: OD****************** and on **th Oct'**, my previous order got canceled. Again now for this order which I placed on **th Oct'** delivery date was given as **th Oct'** and till now they have not delivered. This time it reached the nearest hub to my address. It is not even stuck at the mother hub and has not even reached any wrong Flipkart facility. Still, they are not delivering. I am repeatedly mailing and calling them still they are not delivering. I also requested them to share the address of the Flipkart facility so that I can pick up the order myself still they are neither responding to my mails and nor calling me. If they cannot deliver then why did they take order?? I have paid the whole amount and they are not delivering and keep on extending dates I would have got interest for that money if that was in my bank. I am seriously frustrated now its been a month now daily pain of writing emails and calling them after buying from them. They are not able to deliver orders despite reaching the nearest hub.I urge flipkart if you cannot deliver at least share the address of the Flipkart facility I will myself go and pick up my order.
