I arrived for a scheduled FAA exam at 1:30. I was told this would be a difficult test to administer (according to the lady at the desk). She then was unable to scan my ID to release the test for me, due to technical difficulties. She mentioned this was an issue for a while "since COVID", but it was apparent there was no attempt to resolve this issue since this issue first appeared, which resulted in me showing up to a facility which was unable to actually administer the test I signed up for. She proceeded to speak with technical support for 90 minutes while I sat and waited. She then finally dismissed me having not given me the test and very little instruction on how to proceed to reschedule this exam. Including the 30 min each way drive to the center, I wasted 3+ hours for this completely preventable problem.
