I once drove one and a half hours to a scheduled class only to find the class had been cancelled. they had told everyone except for me, who lived the furthest away.I had spoken to them by phone the day before but they did not mention it and then they got cranky with me because I cancelled the following classes. In other words, I know exactly how you feel and I would advise that you do as I did and shake the dust from your feet and walk to the next place.This generally teaches them to lift their game.
