"Listen to the patient."

When I specifically state that in my address, which is 97a, the letter "a" is vital for correct delivery, because where I live, we have, 97, 97a, and 97b, how, after deliberately underlining this crucial fact, is it possible that my parcel, containing my CT scan appointment and medical prescription, is delivered to 97 and subsequently returned to the royal mail, then after being sent to Belfast, to be relocated, it finally arrives on my doorstep three weeks after the appointment date. Then after phoning to complain, the staff at Frimley Park, conveniently passed the buck onto "the booking staff" leaving me back on an ever increasing waiting list for a CT scan that I could have had weeks ago. In my opinion, this complete failure to listen to the patient's requirements is indicative of a wider problem of our uncaring society.
