Simply awful. Uber customer service basically does not exist. They will advertise delivery times that they have no plans on sticking with. For example, the app will say arrival within 25-35 minutes, but as soon as you click buy, it will immediately change to 1 hour+. If you try to ask for help it moves you to a generic page that says "we're trying our best". If they forget to deliver your order entirely they will never refund you. Awful. This company shouldn't exist.
