I don't know about US but in India the process to review cancellation fee doesn't require interacting with support but rather a two click process to state the reason for cancellation. Works quite well and the only time they don't refund is when you do it too often in a short span of time.
Which goes t to show the mass amount of this happening in India. Ilived there in 2017, drivers didn't understand what Pool was and let everyone out at the first stop.
