^^^^ This. Neither does the company arbitrarily changing FM1.

get your cab, submit for reimbursement, and if it doesn’t get paid then submit a contract dispute in DTS. The clincher here is to make sure you have good evidence for DTS ie screen shots of when you arrived curbside with a date/time stamp, and screenshot when you called for a cab after 15 mins with your call logs showing you made attempt to contact the hotel curbside.

Where disputes fall over is lack of good evidence.
