"ask to be treated else where"

I had an appointment at 11.15 am, I got there at 11.00am booked in and was told to take a seat, which I did, several other people came in after me and booked in, they were also asked to take a seat which they did as well then the nurse called several people through but not me, after 30 minutes I went back to the reception desk and asked what was going on, I was told to go to the nurses station were I was directed to a waiting area and I waited for another half an hour before asking a nurse what is taking so long only to be lied at. I told the nurse that they were lying, as I was told that there is a problem with the computer and that we would have to wait until it was sorted, then they called in someone else which came in after me into the consultants room, I asked the nurse again what was going on and they said we are still waiting for someone from IT to sort it out, they didn't bother to tell anyone what was going on until I spoke out. then they told me and other people what the problem was and then the nurse then called another person through. I then got up and told the nurse that they were lying again then gave them my appointment letter and told them to rebook an appointment and walked out in disgust
