MetroAccess complaint: MetroAccess referral to Yellow Cab Abilities Ride service

I booked a MetroAccess round trip for 16 November 2022. I received a text from Yellow Cab stating that their company was going to fulfill the trip through Abilities Ride. I called to the trip, as Yellow Cab requested on their website. I called back at the opening of the arrival window to re, and was told that they had not yet located a cab, and they would contact me when they did. My concern is that this company apparently is not able to honor the terms of the contract, because this late arrival or failure to arrive has occurred on several occasions. I contacted MetroAccess Where’s My Ride immediately upon being notified that Yellow Cab had not identified a driver for me, and the Where’s My Ride agent booked an Uber vehicle while I was on the line. I am concerned because this coninued failure in service provision causes disruptions in my own attempts to see to the needs of my relative who is in long term care. Simply refunding the cost of the trip is insufficient if it doesn’t result in a change of behavior on the part of the contracting cab company.
