This. Exactly. The spoofing of the first 6 numbers started about a year ago. It's been relentless. When I'm not working and angry, I will keep them on the phone for 20 minutes acting like a mark, then tell them why I did it. Sometimes they hang up, sometimes we have a short conversation, sometimes they get angry and start yelling (and I hang up). I do get less calls now, after having done this about 20 times. In fact, I just realized I only got 2 in the last week (instead of 15+).
