Thank you so much for reaching out. At this time, there is not currently a way to block an entire phone number prefix but we are aware of the nuisance of telemarketing and robocalls and are working to get them stamped out. Currently these methods of call management are available: Manage call security and privacy and you also can add your number to the Do Not Call List: National Do Not Call Registry. And while I know that far more solutions are needed for this issue, we have been and will continue to work on this. I appreciate you reaching out and please let us know if there is anything else that we can assist with in the meantime.
I guess that is an "answer" I believe that phones have become an intrusion into our lives and the fact that we can't better control the nusiance that they have become is somewhat dissapointing.
Thanks for your time.
