Flipkart — I am complaining about not receiving an order's confirmation or details.

Date of incident - 26/12/2023
I am filing this complaint due to the inconvenience caused to me from a recent order.
On 26th of December as I was leisurely scrolling through my Instagram stories, I saw an advertisement with the header of Flipkart on it. It displayed the offer for buying an iphone 14 for rupees 491. I ordered the product and did not receive a confirmation and did not even get the order details about the order.
I expect a confirmation on the order or a refund the payment.
