When I decide to answer, I don't say hello. I answer by saying "I'm not interested in what your selling" and hang up. I've been pretty lucky they don't me back.
The actions from this number are a strong indication they are just looking for valid phone numbers. No One has gotten any person or even robo person. Entire area code is blocked.
this is the third call from them recently, three different days. i have received called from them in the past as well. CID AFLE. Never leaves a message. I will not answer.
