"Appointment cancellation enough to make you ill!"

I have been waiting weeks to see a consultant at the ENT clinic at the Royal Preston Hospital as my appointment was cancelled the day before. I have phoned the hospital twice since and no one can tell me why it was cancelled or when I shall receive another appointment. If I don’t hear from them what is the best thing to do? I thought the law now said that you had to be seen in a certain number of weeks. I was told this by the person on the phone (who did not know how to put me on hold). I told him please don’t cut me off as I had been waiting ten minutes for some one to speak to me. But guess what? Yes he cut me off and I had to start again; this is enough to make you ill!
