"Multiple Cancelled Appointments"

I had to book an appointment via the internet. Once logged on I went through the procedure and selected an appointment time. I clicked on the send to book this time and after a couple minutes got the response that there was problem and that the hospital was aware that I had tried to book n appointment and would be in touch with me within three weeks. After three weeks (by this time the I should have had the appointment) I had not heard anything so I contacted the number on the form to be told that I would need to go back to the doctors and get a new password etc to make a new appointment. This I did wasting my time and the doctors. I asked the doctors to make the appointment as I did not want to go through this again. Eventually an appointment was sent to me. Two weeks later another letter with another appointment arrived. I rung to find out what was going on to be told that the first appointment had been cancelled and they forgot to put it in the letter with the new appointment. Two days later another letter with the same appointment date and this time cancelling my other appointment. I have now had this appointment cancelled another two times. I will be going back to my doctors to get referred to another hospital as I have had a breakdown due to the stress and pain and I find the hospital totally incompetent and no longer trust them
