Remember: It is not only on Halloween that the gremlins, ghosties, ghoulies, long leggity beasties, and things that go "bump" in the night are on the prowl through every kind of telephone communications. They are on the prowl 24/7. In the sense of the classic horror movies, there will be no easy way to exorcise them, as you have seen church people do in those movies. What keeps them going is that they are making money.
Your best defense is to educate yourself, your family, and others about this pestilence. 800notes is an excellent place to start. Good luck.
It's a scam. Their caller stated that the information on the wellness card was incomplete. We got this call once before and talked to the Rite Aid manager in this area. She also stated that they do not call anyone. We do have a Wellness card so someone (a scammer) is getting information somewhere and using it in their little scheme. Wonder what happened to the Do not Call people who are supposed to be on top of this? This was the fourth scam call today!
