Flipkart — Ordered item on 26th January still neither delivered nor got refund

I ordered an item on flipkart on 26th January 2023, which was not even delivered till now. I called them two three times and they have always rescheduled delivery 6-7 times till now every 3-4 days and when I asked them to cancel the order they said they will not cancel the order and rescheduled the item delivery and still showing no option to cancel the item.
