Hello - I have been faithfully going to my online account for months and blocking the robocalls I get - until I got one again from an 800 number I already had blocked. When I spoke wiht Verizon, they explained these outfits can make it look like the same number but it's actually not and recommended using NOMOROBO. Well, I had three robo calls the following day from the usual "local looking" phone numbers and on top of it, the service blocked a legitimate call from the city's municipal call line that can be about anything from trash pick-up to snow emergencies. No good. Verizon was of no help. They referred me to cancel via the DONOTCALL number. I found like you that NOMOROBO was crazy inaccessible, but I persisted and managed to sign back in at https://www.nomorobo.com/ and then move to my own account at https://www.nomorobo.com/phone which has a dashboard and a page to "Add, remove and setup your phones here." We have two landlines that I had enabled with the call blocking. When I clicked on one number at a time to disable NOMOROBO, I was given instruction on how I first had to go to Fios® DIGITAL VOICE and delete a phone number that appears there for Calling Features >> Simultaneous Ring. I deleted the 888 number (who knows what that has to do with but it worked) Once I did that, I hit NEXT at the bottom of the page, and that led to another page that generated a test call to that number confirming I had disabled the service. I repeated the process for the other line. Now they both changed from green "protected" to red "not protected." Frankly, I plan to continue from here to just go up to Verizon each day and block calls that didn't leave a message. Done, end of story. I wish you luck in doing this as well!
I'm so sorry that I did not get to read this first. The number of robo calls went up immediately after I signed up with nomorobo. The only way I can battle the robocalls is through verizon's block list, but that block list is difficult to use, often frozen and is limited.
