Sorry Andrew you need to know the law before you comment. You "can" tell them to stop calling you regardless of if you owe the money or not; if they purist after your request, you can sue them and register a formal complaint with your states Secretary of State! There are laws to protect you! A debt correction agency has no more rights than any other individual to harness people; they are only a representative, and are being paid to recover the account passed on to them, regardless of the accuracy of if the money is owed or not!
