"Failing service"

The most important tests that were supposed to be done, according to my appointment letter this time, couldn't be done. Apparently all the clinicians had resigned, and so the tests that could be done by the assistant staff, who remained faithful to their job, were done, and the others were abandoned. So I have not received the expected service, and any needed treatment resulting from those tests are presumably abandoned as well. I could easily have driven to and from my appointment, as no invasive tests were done, but the appointment letter, which hadn't been updated following the foreseeaable no-show of the clinicians, still instructed me not to drive to the appointment. Whilst the staff were doing their jobs surprisingly efficiently and cheerfully, given the situation they and their patients faced, the service is clearly failing.
