well instead of doing all this mail fraud and "internet charges" which I have never heard of, you need to instead, find the county that Sam lives in, go to that county's website or search for small claims court + count name, there you'll need to get some information about the small claims process is, most states will let you file electronically, but basically you need to file a small claims case against SAM.

Sam sounds like the type that will ignore things, so more than likely he'll ignore the small claims notice against him, and then you can request the court give you a default judgement, which in this case would be easy. You won't have to go to TX, you can do it all over the phone/fax.
