I received several calls from them. I asked for a supervisor. the guy said he has one but wouldn't put them on the line. I harassed the guy about wanting a supervisor until he hung up on me. Did some research and found some info on the caller. It's a home. I searched it and found out it's a cell. Saw a satellite view of their home online. Total scam. Don't buy anything and don't accept their free offers. Magazine BS.
Hope this helps anyone who needs it.
