Delivery Confirmation Flow

Hi Guys,
I was designing the Food Delivery Confirmation Flow for a train app.At the time of when the order is dispatched but the user gets his order on time or not.

When restaurant dispatches his food order. and the user will receive he will get a confirmation message.
If yes so order will be confirmed.

If not get his food on the given time
we will ask the user that train reached or not.

if the train will not reach, a user will get a message to wait for the train to reach the station.

if it already reaches the station so we will give a message to wait, till we contact the restaurant also we will give the restaurant number (optionally).

In the Train journey when user ordered food, Its dispatch from the vendor. but sometimes it did not get the food on time or order sent to the wrong passenger, with this confirmation message we can solve this problem.

Please watch the prototype for this design.
