When they ask for your husband, just say "hold on, I'll go get him" or something similar and leave the caller waiting indefinitely. I've found that's the quickest way to keep telemarketers from calling back. Since they usually have a daily quota of calls or sales leads, they hate for their time to be wasted waiting for someone who may never actually pick up the phone.
Girl only identified herself as Sandy and left no info on who she was with other than she's in charge of my renewal subscription. Once I heard the magazine relation, I knew it wasn't legit. She claimed I had chosen a two year renewal-which of course I knew nothing of, then tried to throw a three-year pitch at me. I told her I'd renew at my convenience then she told me I'd be paying $11 more. I deal with the magazine itself, not these offbeat subscription services.
DNC list doesn't mean squat to these folks. Many are just using robo-calling software. Good luck trying to pursue. You can report the number to DNC, and add them to your Call Block list, but that's about it. Since they call about Discover Magazine, I report them directly to Discover's customer service. This has been going on for years, unfortunately.
