Uber India — uber eats charged me for the food that was never delivered.

On 12th august 2019 i had mistakenly placed order from "leon grill - st. Marks road order #61f3b" at 2:59 pm. Since the order type was cash on delivery order was placed without any confirmation. Since the order was placed by mistake, i had to cancel the order and i did not find any option to do in the app.
Within 30sec i had called the ubereats support to cancel the order. I spoke to rahul from ubereats support, i explained the issue and he immediately reached leongrill restaurant within 2mins ie 3:01 pm. However, restaurant confirmed order was accepted and ready for pickup. I now doubt within 2mins of time how can leongrill prepare the order, do they prepare order overnight and send the same order.
Later the order was been cancelled by ubereats customer care and food never arrived. However when i had placed another order same day at 11:37 pm i forcibly pushed for the payment of 234.99 for order made at 2:59 pm. But later the order made at 11:37 pm never arrived even after waiting for more than an hour. Later ubereat!! Cancelled the order giving some reason.

Now i want to know. When i as a customer also most immediately called the uber eats support to cancel an order which was been placed by mistake and those guys did not and later i was been charged for food which never arrived. But now uber eats has all rights to cancel the order at any given time. Ubereats made me strave that night.!!
I need justification here!!

Thanks
