I only realized today that my NCT is due before the end of the month. It comes up every two years, sue me if I forget. I called to make an appointment and was told, "we'll send one out to you". Beautiful. No chance to pick my own time/date/etc.
While I was on the phone I remembered that in the past I had received a reminder about the NCT when my date was approaching. This is how it works with the car tax and the insurance. So, I asked the woman on the phone about the reminder. Her answer was a classic monopoly response, "We only send our reminders when we can".
