Yeah NCNS is frustrating, but I usually just let it slide; no need to write an alert. Usually someone else calls in the interim and I just see someone else. I'm just flexible like that. I never take appointments when a NCNS will effect my schedule/empty pocket book, or upset me because I could be doing something else that I really need to be doing. The times I have been very upset about a NCNS is when I chose to take the appointment instead of doing something I prefer/need to be doing, so I don't do that any more.
However, I understand that everyone's time is precious and most ladies have a packed schedule that involve taking care of loved ones. I can see how for a less time-flexible lady, this would be a serious inconvenience.
My advice to the ladies is just let it roll off your back, always save money and never live appointment to appointment, and take your focus away from the loss and try to manifest a gain to cancel out the frustration. Also Debbie's advice to confirm and be selective is sound. But for the most part NCNS is inevitable from time to time.
I wish you all the best Shay.
