I meant to say to go to the Consumers Union website. They are the same folks who publish Consumer Reports. They are pressuring the telephone companies to block these scam calls automatically. The have done this for some smartphone users; they can do the same for land line phones.
Got call around 10am on Fri 4/15/16 I didn't answer, they didn't lv a msg. So u know it's a solicitation call of some sort. Since they called my cell without my consent , am now registering this # with FTC mobile cpmplaint line. Call is from California 323 npa.
