Never heard of the club before and I'm sorry your having to go through that I would highly recommend the following...
Like it was previously said, Save all correspondence and have your lawyer proceed with contacting them or their legal counsel first, Have him call and speak to these people and I'm sure it'll put some pep in their step on getting you YOUR money. This sounds awful and I would do exactly the same, If you must carry on with using the court system, No one at the courthouse will laugh and not file that's just foolish to think. In all legitimacy this is pretty clean cut,If you have documented your payment and have your info in order with your lawyer then You go to court and show them bastages you mean business. Sorry for the unfortunate! Godbless
