Oh bloody hell ann that's just awful. You see you do need to keep coming on here just to share that kind of thing with us. I would be sooooo frustrated and angry. I suppose I can just about see that H might not answer an unrecognised call, but it doesn't make you feel any better. There is a chance you will be called again for another cancellation perhaps? Do they have your mobile number, and can you keep it on you, in a pocket, or beside you in the house? Would you have been able to get to thst appointment at such short notice? Have you rung the surgeon's secretary to see if you could be fitted in at the end of a session? Beg, plead.... It does work sometimes. I'm not sure whether PALS could help you? I've found them very good in the past when I've spent a fruitless few hours being passed around hospital departments.
I really would get back and see if there's anything you can do, given the difficulties in August. They are human and often try hard to help.
Do come back to us soon. Isn't that what we're all here for? Support?
