"Appointment cancellation and wrong diagnosis"

I came into the out of hours service because my baby was unwell, here they told me that my baby had colic I ended up getting a second opinion from a hospital nearby to be told it was not colic but reflux. The doctor we were told to come and see did not seem very interested at all in being there. On a separate occasion we had an appointment for my baby's tongue tie, we turned up to the hospital on the date and time specified to be told that our appointment had been cancelled, no written letter or phone call was made by this hospital to inform us of this.
