Flipkart — Grocery ordered but not yet delivered even after 12 days

I ordered grocerry items on 24th September, 2022. I got first message from Flipkart on 27th September, 2022 that your order will be delivered on 28th September, 2022. On 28th September, 2022 I got another message informing that the order will be delivered on 29th September, 2022. On 20th September, I got message that the order will be delivered on 30th September, 2022. Every day, I am getting message from Flipkart 'Sorry to let you know that the delivery has been delayed' and material will be delivered on so and so that between so and so time. On 6th October, 2022, I got the message that it will be delivered on 8th October, 2022. And on 7th October, 2022 I got message that it will be delivered on 9th October, 2022 between 6.30 am to 9.30 am. Regret why Flipkart is taking this much time? Why they assure every day? I have already paid Rs. 1066/- vide internet banking. But not receiving material. Please look into the same and see that the material delivered to me without further delay
