Are you tired of getting phone calls from Brigette from card holder services, or other pesky solicitors?  You already know that registering for the "Do not call list," does not work,  and when you ask them to stop calling you, they ignore you or just hang up.  But, this will stop the nuisance calling.   The ‘Block Now’ button is located on the top of the unit.

Use this feature to block unwanted callers as they are calling you
