I have already recommended it to anyone who is disturbed by robo calls - all my friends and even people who I do not know just passing in a store if it is mentioned

This is a highly effective service. It has blocked so many calls to my home phone. At first I checked every call that didn't make it, worrying important calls might be blocked. Each and every time it was a spammer. I still have a few that get through once in a while. Is there any way I can report those to you for possible inclusion in your blocking service?Thank you so much for this invaluable tool, ... Dee
