This is a number posing as a collection agency for Check N Go, a business i have never done business with. They begin to harass you and when you ask for a proof of the debt all they say is look in your checking account. When you ask them to remove you from their list and hang up they call you back and act like the call was disconnected. You ask for a supervisor they say they ARE the supervisor. No collection agency is allowed to act like this under federal law.
