Hi,
I wanted to share some information about cease and desist letter so that you are able to cover your bases.
After you send the cease and desist letter, the whole action takes a legal shape. It means that if a company is intending to take a legal action by suing you, as they are not able to collect the debt from you, the cease and desist letter actually favors them to file the suit immediately. That is why, it is very important to keep some alternatives open, like the contacts should be made only through mail.
