"Discharged from care without my knowledge"

Recieved letter from my consultant's secretary saying my appointment was cancelled due to unforeseen circumstances and that I should please phone appointments to rebook. On phoning, I was told I had been discharged. When I asked why, I was told I had cancelled numerous appointments. I ask when these were as I always attend as I need treatment for a degenerative disease. I was told they could not help and I was to ring his secretary. When I called, lo and behold, there was no answer. I have now made a complaint. Is this how this hospital treats patients who need help and pain relief? In my opinion this is shocking care.
