If the bus supervisor had hung up on you, you need to move up. You did the right thing calling the supervisor first. Follow the chain of command and just keep moving up until you get some satisfaction. Call the superintendent of schools. The supervisor should take this very seriously, and if he doesn't then you need to complain about him/her also. You can request to be put on the board agenda if all of this doesn't work. Pretty time consuming, but it may keep others from being put in the same situation. Let us know how it goes.
