If my pastors are scammers, can I turn them in? Who would I report them to?

I know you need evidence and I will do my best to get it. I've yzed alot of unusual things in the church and I've had sources inside the church inform me how these so called "pastors" (they don't even have a title or degree). Let me tell you about the church: it's new, small (about 15 members attend each Sunday), four years running, no official building just a borrowed section of a big church. They recieve 2K a month. from a Methodist conference. I've know the pastors at a personal leve, I was friends with them long before the church started, before they established their church or "buisness" they were very cheap. All the sudden they began living a "life of prosperity" got new car, went on vacation all the time, house was remodeled, brand new iPhones for the kids. They began pushing people to give to "God" using a false prosperity gospel. Here's a example of their so called "prosperity": months ago they said they would finish paying their house in 5 years, somehow they finished paying their house in less than a year! According to the pastors brother, he earns as much as he does (which is not alot) in his secular job (which I'm sure he uses to cover up his tracks). I'm not making things up, even his PARENTS are weeping in seeing their son using religion to scam people! And no one is willing to do anything!
