I have used SuperShuttle in Denver for a number of years, relying on their shuttle service from DIA to my mom's house in SE Denver. NEVER AGAIN! I used their service the weekend of January 12th, 2019. I reserved and paid for my round trip service a week ahead. My shuttle service from DIA to my mom's house on January 11th was fine. However, the trouble came on Monday January 14th. I got a notice on my SuperShuttle ap that my shuttle was coming for my scheduled pickup at 3 pm. At 3 pm, I received a text that said "Due to unfortunate cicumstances we are forced to cancel your reservation due to no vehicles in the area, fully refunded. Thank you. Dispatch TJ". I was shocked to be canceled at the last minute. I called and talked to the dispatcher, telling her I had paid for this ride and was relying on their service to get to the airport to catch my flight. She said there was nothing she could do. I had to call a taxi and paid $77.85 to get to DIA to make my flight. I submitted a complaint, and SuperShuttle's response was to refund my payment (so what - by law they have to) and a second email "To encourage you to ride with us again I will be issuing you a one-time discount code for 10% off on a future travel." REALLY??? What shoddy customer service. DO NOT USE SUPERSHUTTLE DENVER. They will hear more from me demanding payment of my unexpected taxi bill due to their horrible service and disregard for customers. There is no excuse for this kind of treatment.
