"Impossible to get a GP appointment"

I have been trying to get a GP appointment at Oak Lodge Medical Practice, Hamilton for weeks to no avail. My surgery only allows patients to book same day appointments by calling at 8am in the morning. This means I've had to take multiple days off work in the hope of getting an appointment. I've tried multiple times and have failed. I urgently need to see a GP and I'm at an absolute loss as to what I do now. I can't continue to take holidays in the hope that one day I'll get through to someone and get an appointment and as I work 50 miles from home, I can't nip out from the  office if I manage to get an appointment. I know the surgery has very limited availability of appointments, but I can't see how refusing to let people book appointments in advance can help.   Even a phone call would be fine. I just need five minutes with someone. There must be many people in my position who face their health worsening as they try and fail to see a doctor. People with mental health problems who work up the courage to try to make an appointment will fail and may not try again. What is the point in the government spending millions on campaigns urging  people to  know  the signs of cancer  and go to  their GP when it's impossible to make an appointment?
