While this organization does provide dance classes at a cost to the students of it's members I can't see at all why it would be considered a non-profit. Everything done is 'for profit'. The force students to pay for the classes they provide in order to be allow to compete in a dance competition (which you also have to pay for). They also pick who will be allowed to win the competition in advance and only allow those that will clearly lose to them to compete against them. If you try to complain...you're complaining to the same people that are doing this so they will just ignore you.
