I paid in advance for transportation from and to the Louisville airport. Driver from airport to hotel was excellent and on time. No driver showed up for return to airport 3 days later despite message that I would be picked up at hotel at a specific time. I waited outside 45 minutes in the heat and no show. Have contacted the company by phone with case number etc, to get refund. No one has replied. I will never use Super Shuttle again unless I get satisfaction on my application for refund.
