I was also told that I need to attend the appointments if I want to keep my pump, and they are scheduled every six months. Saying that, I had to reschedule one because I was ill, and the next one they gave me was six months later, but that might be because I had already had my blood tests done and they were all fine. At my clinic I make the next appointment before I leave - did you leave without seeing the receptionist perhaps?
It has occurred to me, I must admit, that if I don't turn up, how will they get the pump off me? But then again, they could stop paying for the consumables so I'd be over a barrel really.
Apart from the blood tests, I have not found the clinics helpful at all, in fact I feel as if I am giving them more information than I'm getting. The consultant did discover my thyroid problem though, although I guess I'd have gone to the GP eventually.
