[Resolved]  Flipkart — Prepaid order not delivered and no refund

I ordered some grocery items on flipkart grocery on 28jul2022. I made the payment from flipkart gift card (means the order is prepaid), the delivery date of order was 29jul2022.
On 29jul I got a sms that my order is out for delivery, and in evening my app showing me that order is delivered.
But nothing was delivered to me.
And no one contact me on my number to deliver the order.
Now I have no idea to what to do.
My order no. Is OD[protected]
Now I want my money back.
