Great service! Thanks.

What can I say? This is the best deal in a long time. It really works and am so grateful that I hear one ring, and no more. If anyone doubts this program, please get your friends, neighbors to sign up. Thank you so much for this program. I have gotten my friends to sign up. They love it

NOMOROBO has done a splendid job of blocking these idiots even when they spoof numbers. They are relentless! I have thanked you in the past and again expressing my appreciation for this service. When these calls get through by spoofing numbers we report them and you block them until they start using another number. The credit card people actually spoofed my own phone number as their identity to get me to pick up. I get 4 or 5 calls per day that NOMOROBO blocks at an 80% or better rate.

I don't know what the robocallers hear on their end of the line when their call is blocked but I know what I hear on my end--silence. Yes!

It works as described and eliminates robo calls but not not necessary automated calls like some appointment reminders and alerts from my town.

Nomorobo is the best thing - I love it. No more nasty calls all day and into the evening. One ring and they are gone. Thank you!
