It may have been a hiccup, but at least two other people have been caught out.
In both instances, the affected parties said they were told there were no mobility cabs on duty.
One woman who had been taken to hospital by ambulance could not get home when she was released at 3am because no cabs were available.
How helpless would you feel?
In the end, the woman had to be taken home on a stretcher by a sympathetic ambulance driver.
Another couple who had booked a mobility taxi found out when they needed it there were none available.
These things shouldn't happen.
Hopefully with the issue highlighted in this newspaper, the powers-that-be will make sure the service they've agreed to provide is available to those who need it.
We'll be keeping an eye on their progress.
