"Very poor service"

I have been ill for 20 days now and everytime I called in the morning they had no appointments. Asked to give them a call back every afternoon and even then no answer at all. They are closed in the afternoon from 1-3pm. When I called at 3pm the line was dead and I called 20times and no answer. I got an appointment after chasing them nd even then the doctor only took an minute to see me. I am suffering from really bad sinusitis. I told the doctor what I was suffering from the pain I have been having. I was advice to go to dentist and optician. I asked her could I be suffering from sinusitis and she said I could be and just gave antibiotics. I didn’t find her helpful at all.
