Maybe one of your complaints will finally be the one that breaks the camels proverbial back, and finally gets Federal wheels turning at opening BFL's books and prosecuting them to the furthest extent the law allows.
This is the key part. One or two people here and there making a complaint isn't going to make a difference. If hundreds of people make complaints then that will get their attention. That's why it's important that *everybody* who has been wronged by this company needs to make a complaint. The FTC has limited resources and are only going to go after a company that they have received a substantial number of complaints about.
If the feds open an investigation of how this company is doing business it's over for them. The FTC will open a case against them and the likely outcome is that the company would be fined and forced to change their policies. I don't know how much money BFL has extracted from people, but if the fine was big enough it could actually shut them down.
