The only way to spark change would be for multiple people to write written complaints about this providers behavior. It has to be a pattern. So if it is just you that has an issue they will blame you. If they get multiple complaints from nurses about that office, they will be forced to address it. So if it happens again to someone else, encourage them to report it. If you have to call again, and the charge nurse ok's it, maybe do the call on speaker phone (in a private office) with the charge as a witness just in case of more bad behavior.
