Doctors appointments

Why is it so difficult to book an appointment with a doctor these days?
Spend ten minutes on the phone only to be told that 'we are now closed, we are open between the hours of 8 am and 6pm'.... According to my watch it is only 1pm.
It appears that they will not take any bookings past 4pm the following day!!!

If you are with Harold Macmillan Centre - Harrow then I suggest you change..
