Flipkart — Regarding Urgent delivery & disgusting service of the order

As I have ordered the Realme C11 (Rich Grey, 32 Gb) with order number OD[protected].As the expected delivery date was 31 July 2020, but the order itself is in Lucknow hub from 24 July 2020. And another thing is we are waiting for our order from the last 11 days (approx) And another thing is that I have made the payment online as the customer care executive asked for that on 31st July 2020 and had made commitments that the order will be delivered on 31st July 2020 by evening and now today it is 2nd of August 2020 and today also my order didn't get delivered as today itself was expected the maximum time is given by the Flipkart.
And now it is showing on my Flipkart app that the maximum time for expected delivery is 8/08/2020.
As it is getting late for my brother's other works without the mobile as regular classes of my brother have started and it is a genuine issue which I'm telling to Flipkart. As of now, I didn’t get such a disgusting service from your people and such unfair trade practices and this type of poor services caused me mental harassment and as of now I’m getting calls from your executive that My order has been canceled due to COIVD-19 scenario and she (contact no. [protected]) wants to refund the money as of now. But I didn’t cancel my order and have done the payment asked for and also suffered mental harassment from such unfair practices all around by service providers.

Why it is getting so long to reach my address which is almost an hour's drive distance. Please resolve my issue and I want my order.

Order is in Name of Vaibhav Tripathi.
