Swiggy — order cancelled 40 minutes after placing it, without customer consent

I placed an order with Swiggy for 3 donuts to be delivered at my place. The order was placed at 9:39 PM. While waiting for the order, at 10:03 PM I was informed by an SMS that the order was cancelled. The reason given by the customer care executive Mustafa was that the items were not available. It took swiggy 24 minutes to realise the items weren't available and then cancelled the order at a time wherein the restaurant closed and I had to place another order at 10:10 PM from a different restaurant, with no confirmation whatsoever that I will get that order.
