I have plagued with about a dozen "spammers" who call my iPhone from time to time. I have assigned each of them as a separate contact and given each a a name (Spammer 1, Spammer 2, et cetera), and I have them "blocked" through the iPhone app. I'd like to combine all these pests into a single contact, list all their numbers within the contact, and have them in a group as "blocked" callers. I tried to do this, but their calls were not blocked. Suggestions? Thanks!
