Flipkart — Delay in delivery at promised date

Dear Sir/Madam
initially i ordered an item from flipkart on 27 th july and the expected delivery promised date is on Aug 6, 2022. but the delivery didn't happen .
when i contacted the flipkart team they've said that due to technical glitch your order was unable to deliver an kindly please cancel the order make new order.

as per them, i have placed new order on Aug 7, 2022 and promised date was Aug 9, 2022. suprisingly they have said that change the date of delivery so that you could except earlier.
