Flipkart — Delay in delivery wantedly

Exactly 2days back, I have ordered an redmi 9power mobile worth rs10500.
At that time the delivery time is about two to three days they mentioned.
Today morning 6june 2021, i have received an notification that your product is arriving today.
But the delivery person not come to the place. But he visited very near to the place that I have ordered an product.
I think the delivery person is wantedly delayed the delivery time.

In the evening itself I received an notification about the product delivery
Which is from 6june 2021 to 11 June 2021

Suddenly why that much of delay I can't accept it all.
It's okay its corona pandemic time all that is well.
But they delivered the product on time in pervious order.
But this is wantedly they delay the product.
