"Lack of organisational skills regarding an operation"

My husband arrived at 6: 20 in the morning following instructions on a letter he received about his operation for emergency removal of gallbladder.   On arrival a healthcare assistant took his name and details.   When they checked through the names for this morning his name was not on there, checked further to find that it was down for this afternoon.   We were asked if we were told to come at 7am which luckily enough we had brought the letter to confirm the appointment.  

Now my husband hasn’t eaten since 9: 30 last night and not drunk since 6: 30 as per instructions so obviously not happy.   We were not the only ones that this happened to today either.   This whole system needs to looked at.   Even when they rang my husband two days before they didn’t mention the possibility that it could be this afternoon.   Not good.   The consultant wasn’t even here to apologise in person so even if my husband’s op had been booked for this morning he would have been seen on time.
