The pickup window is 10:00 PM the night before your scheduled pickup date to 7:00 PM on the day of your scheduled pickup. This allows for maximum flexibility of driver scheduling and in case any delays are encountered on the route.
If you're unsure if your driver came by, you can submit a support form here or contact a Customer Experience Specialist via LiveChat on the website (bottom right hand corner, available 8 am to 4 pm MST).
