"Cannot get Appointment"

I have dangerously high blood pressure, I have tried to ring, but today was the last straw, I rang from 11.20 to 12.35 they did not answer the phone, they must have gone to lunch with me still hanging on the phone, I walked up to the surgery from the other end of the village, only to be told there are no appointments, why don't you try ringing the receptionist said!!!!!!!!!! this is not the first time this has happened. What's going on with this surgery? it used to be so good.
