I think I'm in the minority here, but I think you have reason to be frustrated. I'm not sure it is worth leaving a gym over, but I definitely think that I would expect my daughter to move up if she had all the skills for level 5 and such a successful level 4 season, especially with your competition season not starting until Jan. In an ideal world, move-up decisions should be made in the best interests of each child, but I'm skeptical that always happens. I think coaches also consider being competitive at meets as a team, the number of girls competing each level, which parents they can risk offending, and other issues as well.
