today i received a letter dated 6th March for an appointment on the 7th March...the letter was posted on the 7th of March, how is it possible for a patient to know about and attend an appointment on the same day the letter is actually sent! I can not believe this has been done, this appointment is with a surgeon, i have been waiting for this appointment for quite some time, and now it will go down as a DNA. Annoyed does not begin to cover how i feel! In my notes are phone numbers for home, mobile, work also email address.. did the person typing this letter not think that it is a physical impossibility for the patient to attend, when the letter is not posted until the day of the appointment.
