"Complete chaos"

I was referred by my GP several months ago. Not having heard anything I revisited my GP to enquire. The doctor told me that

I had not attended the appointment. I told the doctor I had not received one. The doctor confirmed that my details were correct and re-referred me. Nothing. I rang several times and each time, including clinic times, I hit an answering machine. No human contact. I persevered, leaving repeated messages with my phone number, hospital number etc. Nothing. Not even a courtesy call. A total waste of time. I am not impressed. This is the worse treatment I have experienced with the NHS. You can't even talk to these people and they are apparently not interested in you.
