Received a letter advising me to book in for annual check, which I delay for a couple of weeks while I fix an appointment for ears to be syringed (at not inconsiderable expense). I receive a hastener and telephone the same day to fix the appointment only to be advised they don't have any and are fully booked and they'll phone and let me know when they have one. When I ask how long they estimate that will be, I am advised about November (at least two months hence). Not impressed - a case of central office sending out letters without checking availability with their operatives?
