I've got to the 'confirm booking' page now about 20 times, and when I click confirm it tells me that one of my appointments is unavailable and to rebook it. Which I try to do, only to find that there's either no new date available or there is, but at a centre I can't get to because it's too far away. I've been refreshing and trying since about 7am and also yesterday evening.
Anyone else having similar problems? Is it a glitch or just that the appointments getting snapped up too fast for me to book one?
