"Outpatients Appointment Error"

I have 5 young children under 7 years old and travel to PMH regularly. I was sent out 2 appointments on 2 different dates for the same clinic. I phoned and inquired and they said there was possibly an error and to bring the letter with me to the first booked appointment. I arrange 3 siblings school transport arrangements prior to travelling 1. 5 hours via public transport (train and bus) with my 1 year old twins. I arrived on time for my early appointment and checked in at the desk. The appointment was a double up error and the second appointment was cancelled. I then sat to be seen. We waited about an hour then I was told the clinic was running about 40 mins late and to take a wander. I went and grabbed a coffee, went to the gift shop and returned to the waiting area. After a further 15 minutes we were seen in the treatment room, only to be told that the booking was meant to be with the craniofacial plastic surgeon. Not at the the treatment rooms. So as a mum of 5 with young twins, 2 children with care needs and a small business from home... this really was not appreciated. My day... planning for children... Somethings going on with your booking.
