Why would you file in small claims court? You would be giving up a lot of extra money. Not to mention that unless you live in the same state they do, you will have a much harder time collecting. Then of course there is the problem with whether the small claims court judge would be well versed in Federal law.
You need to send them a certified, return receipt debt validation or cease and desist calling letter (think of it as the best $6.47 you ever invested). You also need to report them to the proper agencies to which I have provided links to. Then you need to go out and get a consumer lawyer to sue them on a contingency basis (no money out of your pocket) and let them pay you for the harassment. If everyone did these three things, these crooks would be bankrupt and we would all be the richer for it. Use these web sites to find an attorney in your state that will probably take the case on a contingency basis (no money out of your pocket up front): http://www.consumeradvocates.org/
