Flipkart — Lost my order, Did not receive order and Flipkart has updated as Delivered

I ordered some groceries from Flipkart on 31/07/2022.
Expected delivery date was 02/08/2022
Through EKart
Nobody has come on 02/08/2022 for delivery but Flipkart has updated Order Status as "Delivered"

I tried to call delivery person he said he will come in some hours
I called him on 03/08/2022, he said he will come.
But nobody has come.
I lost my money (prepaid)
I am unable to cancel order.
