Maybe I have been lucky, but I have had very good NHS service over the last 12 or so years.
Starting with Menieres, my consultant, once diagnosed, offered me an operation to stop the dizziness in two days time. Couldn't do it, so a week later. He used gentamycin, or rather the side effects of gentamycin to kill the little hairs in the semi-circular canals. Ok much reduced hearing, but no more dizziness.
The gall-bladder operation was done fairly quickly because I let it be known that I was available at 24 hours notice. That was a comical one. I started off with my Northern Irish GP, taken over by an Asian consultant, passed on to a Polish surgeon, and on the day dealt with by his registrar who I can only describe as a rather dapper black African (absolutely no offence meant). The only doctor who was English was the anaethetist. This, by the way, is in North Cumbria.
Then the heart attack. Once I "pressed the red button" I was whipped in to my local hospital, then transferred to the other hospital, had two stents fitted, and back out exactly one week later.
And now the lung cancer. Reported the cough to my GP, two days later had an X-ray, followed by urgent attention to remove some of the liquid in my chest, a CT scan and then a meeting with the Respiratory Consultant at which point I was given the bad news. All within 2 weeks. That was followed by a referral to the Oncologist and placed on a Chemotherapy drug within a further 3 or 4 weeks.
All in all, I have been very pleased with the NHS service. And most importantly I have been struck by the friendliness of the consultants, most of whom introduced themselves as Hello, I'm John Doe, or whatever.
