Request for removing the comment of the phone number

This number has been calling my home phone for the past month. I never pickup unknown numbers and my voice mail is mechanical. They leave a message to say that they have a file with them and that I should call back. I never will unless I use a pay phone, which I have not done yet. It is spam or hackers trying to get info to steal. Stop calling. They are also associated with the number 716-478-0816 out of Lockport, NY.
