I received the satcam letter from dish network claiming i purchased codes to obtain their services. I did so unknowingly of the situation and the person that was selling it said it was all legal. When i found out it wasnt i cancelled my subscription and placed a chargeback on my credit card wich refunded me my transaction except for 1 that i missed which is the one dish network is accusing me of wrong doing.
Your question is more in line with trademark infringement and telecommunications, so I also directed you to that area. Trolling actions, and the dunning letters that precede them are a regular routine for cable, dish, and other "on-line" providers to protect their valuable, although intangible, assets. While they may be technically correct, you have defenses. Often, a proper response will lead the trolls to understand that you are not worth the pursuit.
The law is complicated and although the facts expressed may seem to be all that is relevant, there may be many other important facts to consider. Also, the law is constantly undergoing change, so what may be correct today, may not be accurate tomorrow. Only a full consultation with an attorney experienced or knowledgeable in the specific legal subject matter is likely to result in the optimal course of action.
