I finally got around to calling GS today regarding the latest junk mail. As I was dialing, I noticed that it was addressed specifically to Chris. When I talked to the nice lady at GS she confirmed that Chris' name was not on the "no solicitations" list in the computer, although mine was. Shame on me for not thinking about this possibility last time I called. Hopefully, this will put an end to this stuff (again).
I have to say that the GS folks I've talked to about this are very nice, helpful folks. (I too have been very civil in my calls).
