Appointments are impossible
When you get an appointment, you've got a roulette - good GPs and bad GPs both. But the booking system is slow, deliberately obtuse, reads a long disclaimer and set of options before you can book anything, and it is basically fully booked within minutes of each day's opening times. As it doesn't open until after I need to go to work, and there are NO options for asking for an appointment in the next couple days, this screws me (and others) over regularly.
