2026 Mar 24 * 2026 Complaint Uber service Dispute charge.pdf TMo
Complaint about Uber service and Dispute related charge
I am disputing $103.94 charge for lack of proper Uber service and undisclosed justification; namely, last-minute cancellation of reserved ride at 7 AM on Feb. 25, 2026, and 25 minute delayed, substitute ride with increased cost, to O’Hair Airport, causing anxiety and stress, as well as additional, repeated Uber Chatbot’s time lost and frustration without promised resolution, see details and screenshots below.
If this complaint is not investigated properly in reasonable time and the full charge is not credited by Uber under the circumstances, I would dispute the credit card charge and request all relevant information needed to verify if any discrimination, malpractice or negligence happened, and if needed to request unbiased arbitration or/and litigation.
My wife and I reserved and pre-paid $86.93 for Uber ride at 7 AM on Feb. 25, 2026, from our home in Sycamore, IL to O’Hare Airport (about 55 miles), for our vacation in Honolulu, HI.
At 6:08 AM while preparing and waiting for the ride, at Uber App our reserved ride was reconfirmed with the message, “Get ready for your [reserved] ride: Daniel Tesla Model Y - 1GN6934. Screenshot_2026.02.25_06:0820_Uber.jpg (see the screenshot elsewhere).”
Since Uber did not come at 7 AM as reserved, I looked at the App at 7:04 AM and was very distressed to see the message, “Sorry for not meeting your expectations: Screenshot_2026.02.25_07:0447_Uber.jpg,” since from our remote and small city Uber is not always available, the reason we reserved the ride in advance.
A substitute ride was not available immediately, so we were worried if we would miss our flight, but luckily a substitute ride came at 7:25 AM from a neighboring city and Uber charged us $103.94 for 25-minute later ride, more than reserved cost, as if we were responsible for the lack of Uber service.
I wanted to know what the reason for the Uber last-minute cancelation was. Was it some kind of discrimination, business negligence, or some malpractice, in order to request explanation and fair compensation, since the more-expensive substitute ride was 25 minutes late and risking rush-ours delays and missing the flight. If we had not not shown for the reserved ride, then Uber will charge us penalty fee up to the ride cost.
When contacting Uber after the ride (Feb 25, 2026), I wasted a lot of time with their AI Chatbot and the promise to be contacted to resolve the unexplained late cancelation and increased cost. Instead of fair resolution, I received a “We are Sorry…” email later. After our vacation I contacted Uber again (Mar 16, 2026) but had been further inconvenienced and frustrated with the same useless communication and new promise by Chatbot that my case will be investigated and resolved, but in vain. When I asked to talk with Customer Service, the Chatbot messaged me that Uber does not have live customer service but is working to establish one soon.
Respectfully and sincerely,
