Verizon recommended Nomorobo to put a stop to unwanted phone calls. I signed up and immediately started having 10X more problems with unwanted calls than before. I also installed the app on my Android phone (BEFORE READING THE REVIEWS) and got a pop up message alerting me that my phone was heavily damaged by viruses I picked up by visiting adult sites. The alert included a button to click to remove the viruses. Well, just so you know, I've never visited an adult site, and I know enough to know when I am being scammed into downloading malware. I went back to the Nomorobo site and tried to delete my account, but guess what? You can't delete your account. You can "delete" your phone number, but they keep your name and email address. And guess what else? You can't call them. I sent in a ticket and requested that my account be deleted, and guess what happened? I receive an automated reply that was utter nonsense. Verizon should warn readers against using the product instead of encouraging it and allowing integration with it.
