I paid for the locker room rental monthly pass using my credit card without getting a receipt. Before the pass expires they treated me rudely and wanted me to stop using the facility. When I refused they called the police. And the the police sided with them and threatened to arrest me and put me to jail if I don't leave. Worst service and practice. Since I didn't do anything wrong, they have no right to treat me like this.
