My experience of NHS 'IT'
My local GP surgery asked if I would mind if my telephone contact number was used to send me reminders of appointments. I said, "Of course not, that's what it's for, to contact me (duh!)"
The following week, the day before my appointment, I arrived home in the evening to find three voicemail messages that had been left at roughly 10am, 2pm, 4pm.
Each message was three minutes long and each was identical: "If you are Mister Frank Ly, please press button 3 now. ", repeated continuously for three minutes. This was their outsourced patient appointment reminder system. It was obviously designd and run by people who had no idea how the real world works and how real people behave.
Needless to say. when I went for my appointment the next day, I told them to remove my contact number from their system and never to give my number to another organisation again. They seemed surprised that I was annoyed.
