Sorry, but I am disappointed. Whilst giving lots of specific dates, and waiting and waiting. Nothing came up. Several times, unconfirmed dates were flagged as possible options but each time I promptly said 'yes' I would receive a message back saying the slot had already gone. I later discovered that it is impossible to book any cancellation slots within 4 days because the system doesn't allow you to. Why, because you might not have time to make necessary arrangements. It would have been nice to have known this before signing up. I went online today Gov website and I searched for cancellation within three days. Nothing immediately available, however, I refreshed the screen several times and a slot has come up for Friday. Today is Tuesday.
