I was leery about using an app without being able to talk to somebody at first. The app is actually very communicative. it let me easily cancel my time and reschedule it twice, which I did because of weather. it showed me the MapQuest of my delivery and how many minutes away they were Isiah and Javair are very accommodating, polite, friendly and listened to my concerns. I will use this app again if needed and refer to anyone else who may need it.
