Fare split broken - support unhelpful

I can never get fare split to work. I end up paying for the entire ride. This has happened 3 times now. I emailed Uber and they gave generic responses and provided no help or apology. "We appreciate your patience" Im using Lyft now. It works better. Update: new problem, price Im quoted does not reflect final price.
