Ekart Logistics — Order delivered on the app but did not delivered to me.

Website:

Flipkart and Ekart Logistics

I ordered grocery items from flipkart and selected the time slot in between 11 AM to 7 PM.The delivery executive calls me and tells me he is coming at 9 PM then he tell me 10:15 PM then 10:45 and then he tells me he is coming at 11:30 PM and when I told him that this is an inappropriate time, I want it tomorrow, he deliberately updated the status in the app to delivered but the items never came to me.When I called him today about the isse he said that the items are in office and he is not coming to deliver them.
