Scumbag stock scam message.  Don't even answer

I didnt answer the call. I get 3-4 spam calls a week on my Verizon phone. I google them first before I bother to call back. Someone posted here and said it was a telemarketer, (TY VM), so I didnt bother to call   I dont get why the phone companies, who know who owns the phone numbers, doesn't put an end to this bull. The few numbers that I called back are usually someone in another state trying to sell a security system. When I tell them I'm on the do not call list, they hang up or claim they won't call again. I always ask, why did you call in the first place? I'm reporting you. Then they hang up. Oh well.
