I don't answer calls I don't recognize, but do look them up to see where they come from. Then I add them to my contacts (for a while) with the name of SCAM, city, state, and a "no ring". I have already used up my allowance with Verizon for numbers blocked. How in the world do these people get away with this. I am also on the government no call list. This is awful that we can't stop these folks. They just find a new number to use or try to disguise it.
