Six months' wait to see your GP for an in-person visit is a worryingly long wait. If I heard someone say that they were required to wait that long for in-person doctor's visits, I'd wonder why they were still seeing that doctor and ask them polite questions to try to figure it out.
Man, it should NOT be permitted to play with the "waiting list" stats in the way you describe. I wish you had someone who gave a fuck about (and could do something about) the problem to report it to... that's just bullshit.
I always find it cute to see what Americans consider a long wait for any medical service.
For myself in Canada the very minimum time to see a GP is a month and a half and that's a best case scenario. Get a different GP? Impossible.
