I had a Dr. try to pull the cancellation fee garbage on me when her office called to reschedual less than 24 hours before the appointment! She wanted to “assist during another Dr’s surgery and it was in conflict.” I flat out told them I can’t come then because I had arranged child care for that time and that time only and couldn’t just come in the next day. They tried to claim I was canceling since I said I wasn’t going to come so I laid into them, and basicaly said if they couldn’t see me when we’d agreed upon 3 months ealier then schedual me for next week and I’ll call to cancel 48.5 hours before. So she said she’d have to check the next week’s schedual and call me back. .Funny thing, less than an hour later the office called back and said the conflicting surgery had been cancelled by the other doctor and the original time was avialable again. Personally, I think they were not heavlily booked and wanted to take the day off but when they found out they weren’t going to get another penny from me if they were just going to jerk me around they changed their minds.
