Those of you who have not received refunds may contact me. I have experience in retrieving fees that were 'stolen' and we were relatively successful in making the organization refund the monies that were taken. I can give you some ideas to help your odds of receiving refunds.
I can also offer some advice, while going to the police may seem like a good idea, you will have problems getting anywhere because the funds were given to the party by your choice. While that may not make sense to you and me, I am just offering my experience in regards to this type of situation.
It is interesting to me though, the problem I had was a smaller scale than a tournament, but when I posted anything in regards to it to warn other softball families, my posts were edited, deleted and I was threatened with 'banishment'. Seems odd that in contrast these posts are so specific in regards to the parties involved.
At any rate, feel free to contact me with a PM and I can give you some details on my experience.
Good luck either way!
