Hello, there are quite a few such things in the gym. This should be reported, because you are definitely not the only one who has been victimized. The gym owner must have reached the filing standard after running away with the money, and you may recover the loss if you catch it back. Even if you don't recover the losses, you can get a few more years.

You can't get the money back, but you can have a little hope unless someone catches it.

Thank you.
