Flipkart — Order cancel without my information.

I order iphone 12 mini (64Gb White) from Flipkart during Big Diwali sale for Rs. 38999/- after claiming offers discounts. Order was on track and reached to the nearest ekart Delivery center.
Since delivery station is nearby to my residence, I went to delivery station in the morning to collect the order but due to heavy rush in the center I was called after an hour or so.
After an hour I got email that order has been cancelled because seller is not able deliver to my location.
This is absolutely rubbish since order is already arrived at nearest ekart Delivery center which within 250 metre radius from delivery location.

when I called customer care, I was told a completely different story.
they told me that thier delivery guy called me and I have cancelled the order which absolutely not true since i never got any call.
